How to Promote an App on Instagram: Setup, Posts, Reels, Ads and Rules

To promote an app on Instagram, switch to a professional account, put an App Store campaign link first in your profile, and post the things your app already produces: each update, each 5 star review, each rating milestone and one feature at a time. Use 4:5 stills and carousels for the people who follow you, a short Reel each week to reach people who do not, and a Story with a link sticker whenever you want a tap. Then read App Store Connect to see how many downloads the link brought.

That is the short version. The rest of this guide is the detail: how to set up the account, every size and limit from Instagram's own pages, what Instagram has published about ranking, eight post formats with examples, 24 post ideas, a 4 week plan for one person, how boosts and app install ads work, the rules that apply to app marketing, and what to measure. Every Instagram fact here comes from a page run by Instagram or Meta, or from a named outlet reporting what Instagram's head said, and each one was opened on October 13, 2026.

This is the Instagram chapter of a larger plan. The other networks are covered in the guide to promoting an app on social media, and the plan around them (listing, pricing, press, retention) is in how to market an app.

Who is on Instagram and why it works for app marketing

Instagram is large and it skews young. Meta's chief executive said in September 2025 that Instagram had passed 3 billion monthly users, as CNBC reported. In the United States, Pew Research Center's 2025 survey of 5,022 adults found that half of adults use Instagram, up from 40% in 2021. The breakdown below comes from Pew's social media fact sheet, published in November 2025 from the same survey.

Four things make that audience useful to someone with an app to sell.

• People see your post on the device they would install the app on. There is no jump from a laptop to a phone between the post and the download.
• Still images work here. In Buffer's study of more than 45 million posts, published in March 2026, Instagram carousels had a median engagement rate of 6.9% of reach and single images 4.4%, both ahead of Reels at 3.3%. You can run a useful account without filming anything.
• Reels are built to reach strangers. Instagram's February 2025 post about Reels ranking says a reel is shown to followers and also to a small audience of people who do not follow the account, and is passed to wider audiences if it does well. The same post says people reshare reels more than 4.5 billion times a day across Instagram and Facebook.
• Use rises with income, as the table shows. If your app has a paid plan, a large share of the people who can afford it are here.

One weakness shapes everything else in this guide. Instagram's help pages document two places for a link people can tap: your profile and the link sticker in a Story. That is why the profile link and the Story routine get so much space below.

When Instagram is the wrong first network

Instagram reaches 19% of adults 65 and older and 37% of rural adults, so an app for retirees or for farming belongs on Facebook first. A work app that is bought by a manager belongs on LinkedIn. If you can record your screen every week and your users are under 30, TikTok may give a new account more reach, and the steps are in the guide to promoting an app on TikTok. The comparison of Instagram, Pinterest and LinkedIn helps if you are choosing between them.

How to set up an Instagram account for an app

A visitor decides in a few seconds whether your profile is a real product or an abandoned account. Six things do that work: the account type, the name and bio, the links, the contact button, the Highlights and the pinned posts. Set them up once, before the first post.

Business or creator account: what each allows

Instagram has two kinds of professional account. Instagram's page about professional accounts says business accounts are best for retailers, local businesses, brands, organizations and service providers, and creator accounts for public figures, content producers, artists and influencers. Use Business for the app's own account. Use Creator if you, the founder, also post under your own name.

Two costs come with the switch. A professional account cannot be private. And Instagram's page on its licensed music library says that library is meant for personal, non commercial use, so certain business accounts do not get it. They get Meta's Sound Collection instead, which that page describes as more than 14,000 royalty free songs and sounds that can be used commercially.

Switching takes a minute. Instagram's setup steps are: open your profile, open the menu, go to Settings and activity, tap Account type and tools, tap Switch to professional account, pick a category, then choose Business or Creator. The category does not decide the account type, and you can change both later. Connecting a Facebook Page is optional. Instagram says it makes sharing to Facebook and running ads easier.

Write a bio that says what the app does

Instagram allows a bio of up to 150 characters. Spend them on three things in this order: what the app does, who it is for, and where to get it. Instagram's own tips for improving reach add a fourth reason to be plain: people find accounts through Search, and the page tells you to put relevant keywords in your bio and captions.

• A pattern you can copy, using an invented hiking app called Trailhead: "Offline trail maps for day hikers. For iPhone. Download below." That is about 60 characters, and a stranger understands all of it.
• Real accounts do the same. On October 13, 2026, Headspace's profile described itself as an everyday mental health app, and Strava's profile as the app for active people. Neither uses a slogan a newcomer has to decode.
• Small teams can use the bio to ask for content. Halide's profile, run by a small camera app studio with about 21,000 followers, says what the team makes and invites photographers to tag their shots with the studio's own hashtag.
• If you put your rating in the bio, change it when the rating changes. Apple's rule on that is in the rules section below.

How to add an App Store link on Instagram (the link in bio)

Instagram lets you add up to 5 websites to your profile, and the page notes that anyone can see them, on or off Instagram. In the app, go to your profile, tap Edit profile, tap Links, then Add external link, and paste the URL. To change the order, open Links again, tap the options menu and choose Reorder links. The help page lists this feature for the iPhone and Android apps only, so do it on your phone.

1. Make the first link an App Store campaign link, so downloads from Instagram are counted separately. In App Store Connect, open your app, then Analytics, then Campaigns, and add a campaign called something like ig bio. Apple's campaign links page allows names of up to 30 characters. If you already have your provider token, the App Store campaign link generator builds the link for you.
2. Use the second link for your website, and the others for things a curious visitor wants: a press kit, the changelog, a waitlist for the next platform.
3. Say where the link is. End captions with "Link in bio", because nothing in a caption can be tapped.
4. Use Apple's wording when you mention the store. Apple's App Store marketing guidelines say an app is available on the App Store or can be downloaded from the App Store, and they ask for one App Store badge per layout or video, at least 40 pixels tall on screen.

Should you use a link page service instead? Many large accounts do: on the day we looked, Headspace, Strava and Finch each sent visitors to one hub page. Halide went the other way and listed its download page first with four more links beside it, and Duolingo's profile showed three links. For an app, the native list is the better default. It saves the visitor a tap, and App Store Connect tells you what the first link earned.

Action buttons, Highlights and pinned posts

• Action buttons. There is no download button. Instagram's page on action buttons lists three for business profiles: Book now, Reserve and Order food. They work through partner services, and only one can show at a time. For an app, the link list does this job.
• Highlights. A story disappears after 24 hours unless you add it to a highlight, and a highlight stays on your profile until you remove it. Create one from your profile with New, choose the stories, then set a cover and a name. A set that suits an app: Start here (a 30 second walkthrough), New (one story per update), Reviews, How to, and Pricing.
• Real examples of Highlights: Headspace names several after the problem a visitor has (anxiety, sleep, finance), Duolingo has one for each kind of course (language, chess, math), and Halide keeps one for quick tips. Each is named with a word a newcomer already knows.
• Pinned posts. You can pin up to 3 posts to the top of your profile: open the post, tap the options menu and choose Pin to main grid. Pin the post that explains what the app does, your strongest proof (a review or a rating milestone) and the latest update.

Instagram post sizes and formats for an app

These are the shapes and limits a post has to fit, each taken from an Instagram or Meta page. The last column says what the format is good for when the subject is an app.

Two notes on that table. The safe margins in the Story row are written for ads, but the same buttons and captions sit over an organic Story or Reel, so they make a sensible working rule for both. And a 4:5 image is the safest single size to design: it fits the feed, any publishing tool can send it, and Facebook and Threads accept it unchanged. Sizes for every other network are in the social media image sizes reference, and the screens you put inside the image are covered in the App Store screenshot sizes guide.

What Instagram says about ranking and reach

Most advice about the Instagram algorithm is guesswork. This section contains only what Instagram has published or what its head, Adam Mosseri, has said on the record. It is direction, not a formula: Instagram does not publish weights, and it says each part of the app is ranked in its own way.

How Feed, Stories, Explore and Reels are ranked

The fullest account is Instagram's ranking explainer, published on May 31, 2023. For each surface it lists the signals it uses, roughly in order of importance, and the actions it tries to predict.

Sends, watch time and likes

Mosseri named three signals in a video in January 2025, reported by Social Media Today: watch time, likes and sends. He said likes count slightly more for posts shown to your followers, and sends count slightly more for posts shown to people who do not follow you. His advice was to watch three numbers: average watch time, likes per reach and sends per reach. Instagram's February 2025 post about Reels gives a similar list (watch time, retention, shares, likes and comments) and recommends a hook in the first 3 seconds.

For an app this changes what a good post is. A post earns sends when one person knows another who has the problem: "this is the app I told you about". A tip most users miss, a before and after, or a tutorial for one job gets passed along. A picture of your logo does not.

Original content, watermarks and reposts

• The ranking explainer lists the Reels that Instagram tries to show less: low resolution or watermarked reels, reels that are muted or have borders, reels that are mostly text, and reels that have already been posted on Instagram.
• Instagram's tips for improving reach say it is less likely to recommend a repost of a reel that is already on Instagram, content with a noticeable watermark, and accounts that regularly collect and reshare other people's content.
• Instagram's page about original content says that stitching clips together or adding a watermark does not count as a material edit, and recommends the repost feature or a Story share when you want to pass along someone else's post.
• What to do: keep the clean screen recording and upload that file, never a copy saved back out of another app. When a user makes something with your app, share it through a repost, a Story or a Collab post, so the original stays theirs.

What does not help, according to Instagram

• A rush of likes in the first half hour. The creator FAQ says reactions in the first 30 minutes do not boost a post's ranking.
• Video for its own sake. The same FAQ says feed ranking does not favor videos over photos.
• Giveaways as a growth trick. The FAQ lists contests and giveaways, clickbait and engagement bait as content that is not recommended to people who do not follow you. Your followers still see it.
• Long Reels. Videos are recommended to people who do not follow you only if they run 3 minutes or less. The limit was 90 seconds until Instagram's January 2025 update.
• Piles of hashtags. The FAQ says relevant hashtags can help and irrelevant ones can hurt, and the limit is now five, covered below.

One check is worth a minute a month. Instagram's page on recommendation eligibility explains that a professional account can open Account Status in settings to see whether its content can be recommended in Explore, Reels, Search and feed recommendations. An account that is not eligible still reaches its followers, but none of its posts are recommended to people who do not follow it.

Instagram post ideas for apps: 8 formats you can repeat

An app that ships regularly produces its own material. Each format below is tied to something that really happened (a release, a review, a number) or to something the app really does, which is why it can be repeated every month without inventing a campaign. The examples use Trailhead, an invented hiking app for iPhone that has just shipped offline maps in version 2.4.

1. App update announcement

Every new version is a post. Put what the user can now do in the headline, never the version number alone: "Maps that work with no signal" beats "Version 2.4". Add two or three points from the release notes and the one screen that changed. Close with "Available on the App Store". Caption: "New in Trailhead 2.4: offline maps. Download a region at home and the map and your position keep working with no signal. Link in bio." Share the post to your Story the same day with a link sticker. Layouts and wording to copy are in these app update announcement examples, and the app release notes generator helps with the notes themselves. Spreadcast designs this post for you each time a new version appears on your listing.

2. Five star review post

A review is the most believable thing you can post, because a stranger wrote it. One rule comes first: Apple's ratings and reviews guidance allows customer reviews in marketing only if the reviewer has given permission. Ask in writing and keep the answer. Then design it simply: one or two lines of the review in large type, the stars, your icon, and nothing else. Do not quote four reviews on one image. Ways to earn more reviews within Apple's rules are in how to get App Store reviews, and a testimonial graphic generator helps with the layout. Spreadcast drafts a post from each new 5 star review and holds it until you approve it.

3. Rating milestone

1,000 ratings, a 4.8 average, a year on the App Store. Thank the users and name the number. The same Apple page lets you use your rating in marketing as long as it accurately reflects the current rating, so write the month on the image ("4.8 stars, October 2026") and unpin the post when the number changes. A post that shows only the rating needs no one's permission, which makes it the easiest proof to publish. Spreadcast makes this post when your listing passes a milestone.

4. Feature carousel: an Instagram carousel for one feature

Carousels beat single images and Reels on engagement rate in Buffer's data, and they are the best way to explain a feature without video. Build five to seven slides: the problem as a question, three or four screens that show the steps, the result, then "Available on the App Store, link in bio". For Trailhead: "Hiking with no signal?", the download screen, the map in airplane mode, the saved regions list, the result. Pick one orientation, because Instagram applies it to every slide. Instagram's January 2025 update adds a small bonus: a photo or carousel with audio added may also appear in the Reels tab.

5. Before and after

Show the old way next to the app. A paper map with a torn corner beside the offline map. A spreadsheet of expenses beside the budget screen. Two slides are enough, or one split image. This format is easy to send to a friend who still does it the old way, and sends are one of the three signals Mosseri named. Keep it honest: the before has to be how people really do the job today.

6. Founder story

People follow people more readily than logos, and a small app has an advantage here that a large company cannot fake. Record 30 seconds to camera or write a text carousel: why you built it, what went wrong, one number you are willing to share. A useful trick: post it from your own creator account and invite the app's account as a collaborator. Instagram's page on Collabs says an accepted collab post is shared with both sets of followers and shows on both profiles.

7. Tutorial Reel: Instagram Reels for apps

• Show one job from start to result, in a 9:16 screen recording, with your voice or text on screen. Fifteen to forty seconds is a sensible length to start with. Recording steps for an iPhone are in the social media guide.
• Put the problem on screen in the first 3 seconds, which is what Instagram's own Reels advice asks for.
• Keep text out of the edges. Meta's Ads Guide for Reels asks for at least 14% at the top, 35% at the bottom and 6% on each side to stay clear.
• Use your own voice or a track from Meta's Sound Collection. The licensed music library is for personal use, and the Ads Guide says a Reel used as an ad should not contain licensed music.
• Test it first if you can. A trial reel is shown only to people who do not follow you, and you get insights within 24 hours. If it does well, share it with everyone.

8. User generated content

• Ask for it in the bio and credit it in the caption. On October 12, 2026, a post on Halide's account showed a customer's photograph, named the photographer in the first line and carried exactly five hashtags.
• Use Collabs for creators. On October 9, 2026, a runner's reel listed Strava as a collaborator, carried a partner hashtag, and appeared on Strava's grid as well as the creator's own.
• Get permission before you post someone's work. Instagram's page about original content says you are responsible for obtaining it.
• Let users share from inside your app. Meta's Sharing to Stories documentation describes how an iOS app can hand a background image or video and a sticker to Instagram's Story composer. It needs a Facebook App ID. Put your app's name on the sticker, and every result a user shares carries it.

24 Instagram post ideas for apps in one table

How to market an app on Instagram in a week with nothing new to announce is the question that empties most feeds. Keep this list next to your calendar and work down it. More examples from real apps, across channels, are in these mobile app marketing examples.

Captions, Instagram hashtags for apps and alt text

The caption does three jobs: it tells the reader what changed for them, it gives Search words to match, and it points to the link. Write the benefit in the first line in plain words ("Offline maps for hikers" matches a search, "Big news" does not), add two or three short lines of detail, and end with "Link in bio". Meta's media reference allows 2,200 characters, and you will rarely need 300. If writing a separate caption for every network is what stops you from posting, the social media caption generator page covers that.

How many hashtags to use and how to choose them

Older guides say 30. Instagram's hashtag page now says: "You can use up to 5 tags on a post." Instagram announced the change on its creators account on Threads in December 2025, as Social Media Today reported, and argued that a few targeted hashtags do better than many generic ones. Meta's reference for publishing tools still lists 30, so a scheduler may let you add more. Stay at five.

Alt text for app posts

Instagram's page on alt text explains that Instagram writes automatic alt text with object recognition and that you can replace it. Before posting, tap More options, then Write alt text. After posting, open the post's options, tap Edit, then Edit Alt Text. A designed app post is mostly words set inside a picture, and a screen reader cannot read those, so the alt text should repeat them: "Trailhead 2.4. Offline maps. A phone showing a trail map with a blue position dot and an Offline badge." Publishing tools can set it too: Meta's content publishing guide has supported alt text on image posts since March 2025.

How to promote an app on Instagram for free: a 4 week plan for one person

This plan assumes one founder, no budget and about two hours a week. It gets the account from empty to a rhythm you can keep. More unpaid channels outside Instagram are in how to promote an app for free.

After week four, keep a weekly rhythm of three feed posts: a still on Monday (the update if you shipped, a feature if you did not), a Reel midweek, and proof or a carousel on Friday. Reshare each one to your Story. That is roughly 30 minutes for the still, an hour for the Reel and 30 minutes for the third post.

How often and when to post

• How often: Buffer's analysis of about 2.1 million Instagram posts from about 102,000 accounts found that a week with 3 to 5 posts lifted follower growth by 0.26% over a week with none, against 0.12% for one or two posts, and that posts in the 3 to 5 group reached about 12% more people each. Buffer treats one or two a week as the minimum that keeps an account alive.
• Instagram's own number is about Reels: the creator FAQ says the creators with the highest follower growth post about 10 or more reels a month, and adds that frequency is only one factor.
• When: Instagram's answer is to post when your audience is awake and most active. Insights shows the times your followers are online once you have 100 of them. Until then, Buffer's best time to post study, published in March 2026, found Thursday at 9 a.m. local time to be the strongest slot for Instagram, Wednesday the day with the highest engagement and Friday the weakest.

Stories and the link sticker

The link sticker is the shortest path from Instagram to your listing. Instagram opened it to all accounts in October 2021, except new accounts and accounts that repeatedly break the rules. To add one, create a Story, open the sticker tool, choose Link, paste the URL and tap Done. Instagram's page about the link sticker says a tap sends the viewer to the linked website, and that the sticker works in organic Stories only.

• Give the sticker its own campaign link, named ig story, so its downloads are counted apart from the profile link.
• Reshare every feed post to your Story with the sticker on it. The feed post explains, the Story collects the tap.
• Save the best ones to a highlight, where the sticker keeps working after the Story is gone.
• Add stickers by hand. Meta's media reference says publishing tools cannot attach link, poll or location stickers to a Story.

Collab posts with creators and partners

A Collab post borrows an audience without an ad. Instagram's page on Collabs says you can invite up to 5 collaborators, the post is shared with each one's followers once they accept, and it shows on their profile as well as yours. Only the original author can delete it, and collaborators can leave at any time. Good partners for an app: your own founder account, a creator in your niche, an app that sits next to yours (a recipe app and a grocery list app), or the user whose result you are featuring.

Two limits to plan around. You cannot add collaborators to a Story. And Instagram's scheduling page lists collaborative posts among the things that cannot be scheduled in the app, so a Collab goes out by hand.

Scheduling without paying for a tool

• Inside Instagram: Instagram's scheduling page lets a public account schedule reels, photos and carousels up to 30 days ahead, at most 25 posts a day. Create the post, tap More options, turn on Schedule this post and pick the time.
• Meta Business Suite: Meta's page on creating posts in Business Suite covers Facebook and Instagram from one screen on a computer, with different text for each, up to 10 photos for Instagram, and an Active times button that suggests slots from the last 7 days of follower activity.
• Both tools publish what you have already made. The design and the caption are still an hour of your week for every post.

How to promote your app's Instagram account on other platforms

A new Instagram account grows faster when people who already know the app are told it exists. Three places do that for free: Meta's own apps, your other social profiles, and the app itself.

Share every post to Facebook and Threads automatically

• Facebook. Instagram's page on sharing to Facebook explains both routes. For one post, tap Also share on before you publish and turn on your Facebook Page. For every future post, go to your profile, open the menu, tap Accounts Center, then Connected experiences, then Sharing across profiles, pick the Instagram account to share from and the Facebook account to share to, and switch on Your Instagram posts. The page notes that the Facebook audience for shared posts can differ from your usual Facebook audience.
• Threads. Instagram's page on sharing to Threads uses the same Also share on screen, with a choice between sharing this post and always sharing posts. Your Threads profile has to be linked to the Instagram account, and a post you later delete on Instagram has to be deleted on Threads separately.
• Both options work in the Instagram app for iPhone and Android, which is where a scheduler cannot reach. If a tool publishes your posts, connect Facebook and Threads in that tool as well.

Post the same work on networks Instagram does not reach

Instagram's sharing reaches Meta's apps and little else. Instagram's page on sharing to other social networks names Facebook, Twitter and a few regional services, and LinkedIn, TikTok and Pinterest are not among them. Its page on sharing existing posts adds the manual routes from a computer: Share to Facebook, Messenger or Twitter, or share by email, QR code or a copied link. So the 4:5 still has to be uploaded again on LinkedIn, as a TikTok photo post and as a taller Pin. Which of those networks deserve the time is covered in the comparison of social media platforms for app promotion.

Point to Instagram from inside the app

• Add an Instagram link in the app's settings or about screen, next to support and the privacy policy. People who open that screen are already users, and they are the ones most likely to follow.
• Put the handle on the screen people share, such as a finished workout, a saved plan or an exported photo, so every shared result carries it. The Sharing to Stories route described in the user generated content section does this inside Instagram itself.
• Use the QR code Instagram generates for a post on a printed card, a conference badge or the last slide of a talk.
• Mention the account in release notes and in the email you send for a big update. A sentence such as "Tips for every feature are on our Instagram" gives a reason to follow.

How to advertise an app on Instagram: boosts and app install ads

Instagram ads for apps come in two kinds, and both work best on a post that has already worked for free. A post that earned sends and profile visits from followers has shown that the message lands, and money behind it buys more of the same. The two kinds are a boost and an app promotion campaign, and they are very different products.

Boosting a post from the Instagram app

A boost turns an existing post into an ad. Instagram's page on boosting a post gives the steps: open the post, tap Boost, then set the goal, the audience, the daily budget and the duration. The ad is reviewed against Meta's ad policies before it runs, and it can appear in the home feed, Explore, the profile feed and Stories. Instagram's page on ways to advertise adds that a boost made in the app sets audience and placement options automatically, and that Ads Manager is where every Advantage+ feature lives.

One line on that page saves real money. If you pay for a boost inside the Instagram app on an iPhone, an Apple service fee of 30% of the ad payment may apply in most regions, and Apple keeps it. Instagram's own advice is to boost from instagram.com in a browser. On a $100 boost, that fee is $30.

Boosting from a computer takes four steps on Instagram's boosting page: open your profile on instagram.com, select the post and click Boost, choose the goal, audience, daily budget and duration, then select Boost post. The ad goes to review first, and Instagram sends a notice when it is being reviewed, when it is approved or rejected, and when it ends. If the boost sends people to a link, use an App Store campaign link named for the boost, so you can see what it earned in downloads and not only in likes.

Why can't I boost my Instagram post? Common boost errors and fixes

Instagram's troubleshooting page for boosting starts with two requirements: the account has to be a professional account, and its owner has to be over 16. After that, most failures match one of the messages below. In the EU, the EEA and Switzerland there is one more limit: the same page says advertising is limited for an account whose Accounts Center has a subscription to use Meta products without ads.

Stories have their own rules, and one of them matters to every app. Instagram's page on boosting Stories says a Story with a link sticker cannot be boosted. The Story you made to send people to the App Store is exactly the one you cannot pay to push. The same page says a boosted Story can carry up to five location, hashtag, mention or tappable text elements, or one countdown sticker, needs a 9:16 shape or one between 4:5 and 1.91:1, and may be refused if the image or video was shared before. For a paid Story with a link, build a Stories ad in Ads Manager instead, where the link is a call to action at the bottom of the ad.

Instagram app install ads in Meta Ads Manager

What people call Instagram app install ads are Meta app ads that run on Instagram among other places. Meta's page about app ads describes the app promotion objective, which shows your app to the people most likely to download it, and says you create these as Advantage+ app campaigns in Ads Manager.

• Register the app and add Meta's SDK first. The same page says you can run app promotion ads without them, but the ads will then optimize for link clicks instead of installs, and the campaign will not track any installs.
• Expect less manual targeting than you may want. Meta's page about Advantage+ app campaigns says you choose country, language and app store, and that targeting by gender, interests, behaviors and lookalike audiences is not supported. Placements are automatic across Facebook, Messenger, Instagram and Audience Network, so an Instagram ad for an app is normally a Meta ad.
• Design to the specification. Meta's Ads Guide for Instagram Feed lists a JPG or PNG at 4:5, 1440 by 1800 pixels, with 125 characters of primary text, a 40 character headline and a Download call to action. Stories and Reels ads are 9:16 at 1440 by 2560.
• Reuse what worked. The still that earned sends as a post is your first ad. A page on ad creative for apps covers the layout.

How much it costs to advertise an app on Instagram

Meta does not publish a price or a fixed minimum. Meta's page on ad costs says you decide how much to spend, through a budget and a bid strategy, and that some advanced ad types have a minimum you are told about during setup. Meta's page on minimum budgets says minimums vary by country and objective, that Ads Manager shows an alert when a budget is too low, and gives one usable rule: with a cost per result goal, the daily budget should be at least 5 times that goal. A $5 goal per install means at least $25 a day.

What an install costs is set by the auction and by how well your ad and your App Store page convert, so nobody can tell you the number in advance. A practical first test is one campaign, one country and one week: at $25 a day that is $175. Fix the listing before you spend it. The order of that work is in how to get app downloads.

SKAdNetwork and iOS measurement in plain words

• Why iPhone ads are measured differently: since iOS 14.5, Apple's App Tracking Transparency rules require an app to ask permission before it tracks a person across other companies' apps and websites. Without that permission the device's advertising identifier reads as all zeros, so an ad network cannot simply match "this phone saw the ad" with "this phone installed the app".
• What Apple offers instead: Apple's ad attribution page describes AdAttributionKit, which builds on SKAdNetwork. Apple itself tells the ad network that an install followed an ad, in a signed message with no user or device identity in it. A tap counts if the install comes within 30 days. The message arrives 24 to 48 hours after the person first opens the app, and finer detail is included only when enough installs share it.
• What Meta does with it: Meta's guide to reaching people on iOS 14.5 or later says an iOS app promotion campaign uses either Apple's SKAdNetwork or Meta's Aggregated Event Measurement as its attribution method. Meta's page on iOS campaign limits lists the limits: up to 24 such campaigns per app, one ad set per Advantage+ app campaign, auction buying only.
• What that means for a small budget: results arrive late and in totals, and a tiny campaign may show little detail. Run one or two larger campaigns, wait a few days before judging, and compare against first time downloads in App Store Connect.

Rules to know before you promote an app on Instagram

How to measure what Instagram sends to the App Store

Instagram can tell you what happened on Instagram. Only App Store Connect can tell you what happened next. You need both, and you need them joined by a campaign link.

Instagram Insights, as Meta names the metrics today

Insights are free on any public account. The overview covers a period you choose within the past 90 days, and the numbers for a single post, Story or Reel stay available for up to two years. Meta now leads with views and viewers, so an older guide built around other metric names may not match what you see on screen.

App Store Connect campaign links for downloads

A campaign link is your App Store link with a provider code, a campaign name and a media type on the end. Apple's campaign links page explains that the provider code is created the first time you make a link and never changes, and that the campaign name is whatever you type. Make one for each place a tap can come from.

Three details on Apple's page shape how you read the result. A campaign shows up at least 24 hours after it starts, and only once at least five people have made a first time download through it. A download is counted when it happens within 24 hours of the tap. And if someone taps two of your links, the most recent one gets the credit. Treat the number as a floor: many people see a post, close Instagram and search the App Store for your app's name later, and those downloads land under search. Compare App Store search downloads on days you posted with days you did not. Search traffic is its own subject, covered in the App Store Optimization guide.

Mistakes to avoid when you promote an app on Instagram

• A plain App Store link in the bio. Without a campaign link you cannot tell Instagram's downloads from anyone else's.
• Thirty hashtags copied from an old guide. The Help Center allows five.
• A Reel saved out of another app with its watermark. Instagram says it shows those less.
• A raw screenshot as a post. Small interface text is unreadable in the feed and worse in the grid preview. Put one screen in a frame with one headline.
• An old rating on a pinned graphic, or a review quoted without asking. Both break Apple's rule, and both are easy to forget in a post from last spring.
• A giveaway to grow followers. It brings people who want the prize, and Instagram does not recommend it to people who do not follow you.
• Paying for a boost inside the iPhone app. Apple's 30% fee does not apply when you boost from instagram.com.
• Install ads without Meta's SDK. They optimize for link clicks and report no installs.
• Posting at launch and then stopping. Feed ranking counts interactions from the past few weeks, and a silent account has none.
• Judging by likes. Read shares, profile activity and downloads on the campaign link. A post with 12 likes and 9 downloads beat the one with 400 likes and none.

How long it takes to promote an app on Instagram

Longer than most guides admit. Buffer's figure above is a fair measure of the pace: posting 3 to 5 times in a week lifted follower growth by 0.26% over a week with no posts. On an account with 500 followers that is one or two extra followers a week from frequency alone. Growth on Instagram comes from the occasional post that travels, and you cannot schedule that post. You can only publish enough good ones for it to be among them.

If six months of steady posting send almost nothing to the App Store, the cause is usually one of three things: the audience is not on Instagram, the listing does not convert the visits it gets, or the posts are about the company when they should be about the user's problem. The first is a reason to move networks. The other two are fixable, and the wider plan for apps on the App Store is on the page for mobile apps.

Where Spreadcast fits

Spreadcast does the recurring still posts in this guide for you. You paste your App Store link once at the start page. It checks your public listing every day, and when you ship an update, receive a new 5 star review or pass a rating milestone, it designs a 1080 by 1350 post from your icon, screenshots and colors, writes the caption and publishes it to Instagram and 10 other networks: TikTok, LinkedIn, Facebook, Threads, Pinterest, Bluesky, Mastodon, Telegram and Discord, plus YouTube for video posts (TikTok posts stay private until TikTok has audited Spreadcast's app). Posts that quote a reviewer's words wait for your approval, because of Apple's permission rule. In a week with no update it drafts a post about one of your features, so the feed does not go quiet. You choose between approving each post with one tap and full autopilot.

That covers formats 1 to 3 above and the weekly feature still. It makes still images for apps on the App Store, so the Reels, the carousels, the Stories with link stickers and the Collab posts stay with you, and Instagram needs to be a professional account for any tool to publish to it. The free plan drafts every post for you to download, with a small Spreadcast mark. Pro is $29 a month flat, with the design, the caption for each network and publishing to all 8 networks included. Instagram's scheduler and Meta Business Suite cost nothing, and they publish posts you have already designed and written. The Instagram post generator page shows what the posts look like, and plans are on the pricing page.
