App Launch Marketing Strategy for Startups, From Before Launch to Day 90

Startup app marketing tends to be planned as one big day. The team prepares for weeks, launches, watches the install chart spike, and then has no plan for the following Tuesday. A marketing strategy for a new app needs three phases, each with one goal.

Before launch, the goal is a group of people who will install on day one and a listing that converts them. In launch week, the goal is to concentrate attention into a few days. In the first 90 days, the goal is to keep showing up while the product catches up with what early users tell you.

The third phase decides whether the first two were worth it. Business of Apps' retention guide puts average retention on iOS at about 26% on day 1 and about 4% on day 30. Most of the people your launch brings in will be gone within a month, so new people have to keep arriving.

Revenue takes time as well. In RevenueCat's State of Subscription Apps 2026, only 17.3% of newly launched subscription apps reach $1,000 in monthly revenue within two years, and the apps that get there take a median of 58 days. Launch day is the start of the work.

This page gives the outline and the timings. For the full task list use the app launch checklist, and for every channel in depth read how to market an app.

A pre launch app marketing strategy has one job: make sure launch day does not start from zero. That means collecting people, and it means doing it somewhere you own. An email list or a TestFlight group is yours. A follower count on one network is rented.

Start with the beta. TestFlight gives you room for up to 10,000 external testers, which is far more than an early stage startup needs. Thirty testers who use the app every day are worth more than three thousand who opened it once. Ask each one what they would tell a friend the app does, and use their words on your listing.

If you have a firm date, consider a pre order. Under Apple's pre order rules, a limited version of your product page goes live on the App Store and shows the expected release date, so every post you make before launch has a real place to send people.

Claim your handles on the networks you plan to use and post a few times before launch, so the accounts are not empty on the day journalists and early users look you up. Problem first posts, short screen recordings and a countdown are enough. The app launch announcement examples show formats you can copy.

Spreadcast cannot help with this phase. It works by reading a live App Store listing, and before release there is no listing with versions, ratings and reviews for it to read. Make the pre launch posts by hand.

Around day 8 the launch attention is gone and the team is tired. This is where most launch plans end, and where a new app marketing strategy has to begin. The work turns from one loud week into a quiet routine.

Updates are the backbone of that routine. Early users report bugs and ask for features, you ship, and each version is a reason to post. For a risky change, Apple's phased release rolls an update out to users with automatic updates over 7 days, starting at 1% and reaching 100% on the last day, and you can pause it.

Consistency is what the networks reward. Buffer's study of posting consistency followed more than 100,000 of its users for 26 weeks. Accounts that posted in 20 or more of those weeks got about 5 times the engagement per post of accounts that posted in 4 weeks or fewer. The data is observational and limited to Buffer users, so treat it as a strong hint.

Measure as you go. Campaign links in App Store Connect Analytics show which posts and channels lead to first time downloads. They become available only after your app has analytics data, and a new campaign appears after at least 24 hours, so set them up in the first week after launch.

In a startup, a post that goes out at the wrong moment is a real risk: the day of a pricing change, an outage, a funding announcement. Spreadcast has two modes for that reason. With approve first, every post waits for one tap before it is published. With full autopilot, posts go out in their slot without anyone touching them.

Each post takes the next free slot on the calendar, and you can drag it to another day. If Thursday belongs to a press release, move the update post to Friday. You can also make a single post by hand with New Post when you have news that is not on the listing.

Pro is $29 a month flat for 1 app, with the design, the captions and the publishing to 8 networks included. Studio is $79 a month for 5 apps with 3 seats, and each app keeps its own brand. Three seats fit a small startup: a founder, the person who handles marketing and a designer. The plans are compared on the pricing page.

The brand kit screen is where the team sets the logo, colors, screenshots and audience once, so the designer does not have to check every post. If nobody on the team designs, brand consistency without a design team explains what to lock down first.

An app launch marketing agency plans and runs the launch for you: positioning, press outreach, launch creative, paid campaigns from the first day and sometimes creator deals. It is the fastest way to get a large launch done by people who have run others.

It is also the most expensive line in the budget table above. The first six agencies in Clutch's directory show minimum projects from $5,000 to $25,000, and paid launch campaigns add ad spend on top. For a funded team with a fixed date and press interest, that can be money well spent.

For an early stage startup, launch day is rarely where things break. The usual failure comes in week two, when the agency's scope ends and nobody posts again. If you hire one, keep the rhythm after launch in your own plan: who answers reviews, who ships the first update and who announces it. The questions to ask before you sign are on the app studios and agencies page.

Everything before the app is on the App Store is yours to make: the teasers, the waitlist, the beta and the launch day announcement itself. Spreadcast starts the day the listing is live.

It works from App Store listings today. A startup that ships on both stores runs it from the iOS listing, and Google Play is next on the list.

Press, Product Hunt, ads, push notifications and App Store optimization stay with the team. So does the launch video: Spreadcast makes still image posts, so keep a video tool for the trailer.

To see which posts lead to installs, use Apple's campaign links in App Store Connect. For everything outside the recurring posts, the two pages to keep open are the app launch checklist and how to promote an app on social media.
