How to Build a Mobile App Launch Timeline: 90 Days Before and After
Most app launches fail quietly. Not because the product is bad — but because the team treated launch day as the starting line instead of the midpoint. By the time the app goes live, the window for easy early momentum has already passed.
This guide lays out a concrete 90-day timeline: 60 days of pre-launch work, launch week execution, and 30 days of post-launch retention. Follow it in sequence. Skip sections at your own risk.
The 90-Day Launch Map at a Glance
Before diving into the phases, here's the full timeline compressed into one reference table.
| Week | Phase | Key Deliverables |
|---|---|---|
| –12 to –9 | Pre-launch: Foundation | Positioning locked, landing page live, analytics instrumented |
| –8 to –5 | Pre-launch: Audience & ASO | Keyword research done, metadata drafted, waitlist building |
| –4 to –2 | Pre-launch: Soft launch & press | TestFlight / Play beta live, screenshots finalized, media outreach |
| –1 | Launch week prep | App Store review submitted, paid campaigns paused/ready to activate, influencers briefed |
| 0 | Launch day | App goes live, campaigns activate, press embargo lifts |
| +1 to +2 | Early traction | Monitor ratings cadence, triage 1-star reviews, CPI benchmarks set |
| +3 to +4 | Optimization | Pause underperforming ad sets, A/B test store screenshots, push first update |
Phase 1: Foundation (Weeks –12 to –9)
This is the least glamorous phase and the one most teams rush. Don't.
Lock your positioning before you write a single ad. Answer three questions in one sentence each: Who is this for? What does it replace or improve? Why should they believe you? If your team can't agree on answers, no amount of marketing spend will fix the confusion.
Stand up a pre-launch landing page with a waitlist. You need a place to send traffic before the app exists on any store. Keep it simple — headline, one-paragraph explanation, email capture, and a rough "coming [Month]" date. Even a few hundred waitlist signups gives you a warm audience for Day 1 and a signal that your messaging resonates.
Instrument analytics before a single user touches the app. This means GA4 for the web funnel, your chosen mobile measurement partner (AppsFlyer, Adjust, or Branch) integrated into the build, and App Store Connect + Google Play Console connected. If attribution isn't set up before launch, you'll spend the first month guessing where installs came from.
Phase 2: Audience Building & ASO (Weeks –8 to –5)
App store optimization is a pre-launch activity, not a post-launch fix. Your app's title, subtitle, keyword field (iOS), and short/long description (Android) need to be drafted, reviewed, and finalized before you submit for review. Keyword research at this stage follows the same logic as SEO: find terms with meaningful search volume and realistic ranking potential for a new app with zero reviews.
What to produce in this phase:
- Keyword list (primary + supporting) for both stores
- App title and subtitle that include your primary keyword naturally
- First draft of screenshots and preview video
- App icon — A/B test two variants if you have the runway
Build your audience in parallel. The waitlist grows through a mix of organic content (short-form video showing the product in action tends to outperform text posts), targeted paid social to a cold audience if you have budget, and direct outreach to communities where your users already gather. A Reddit thread in the right subreddit, done honestly and without spam, can drive hundreds of qualified signups.

Phase 3: Soft Launch & Press (Weeks –4 to –2)
Ship a beta. TestFlight (iOS) and Google Play's internal/closed testing track (Android) exist precisely for this window. Get 50–200 real users into the app, not friends and family who'll be nice, but people who match your actual target persona. Watch session recordings, read their feedback, and fix the top three friction points before the public launch.
Finalize your App Store creative. Screenshots and preview videos are conversion levers that most teams underinvest in. Your first screenshot needs to communicate the core value in under three seconds. Use real UI, not illustrated mockups. Add a short caption on each frame that speaks to a specific benefit, not a feature name.
Begin media outreach — but be realistic about timing. Tech journalists at major outlets work on 2–4 week lead times for app coverage. If you want a story to land on launch day, you need to pitch 3–4 weeks out, with an embargo date. For most early-stage apps, a more achievable target is niche newsletters, podcasts in your category, and micro-influencers with 10K–100K engaged followers in your vertical. They move faster and often convert better than broad press coverage.

Phase 4: Launch Week
Submit for App Store review at least 7–10 days before your target go-live date. Apple's review timeline is typically 1–3 days, but rejections reset the clock, and a metadata rejection at Day –2 is a situation you don't want. Build in buffer.
Structure your launch day like a campaign, not an event. Activate paid campaigns the morning the app goes live. Send your waitlist email the same morning — this is your highest-intent audience and their early installs signal momentum to the store's algorithm. Coordinate any influencer posts to land within the first 48 hours, not spread across a week.
Watch your ratings cadence from hour one. The App Store and Google Play both weight early review velocity. Build a prompt into your onboarding flow that asks for a rating after the user completes their first meaningful action — not immediately after install, which produces worse ratings and lower completion rates. In our engagements, timing the rating prompt to a moment of success (first workout logged, first delivery tracked, first task completed) consistently outperforms prompting at launch.
Phase 5: Post-Launch Retention Window (Days +1 to +30)
The 30 days after launch are when most of your early users will decide whether to keep the app or delete it. This window matters more than the launch day spike.
Set your retention benchmarks in week one. Day 1, Day 7, and Day 30 retention are the three numbers to track. Industry retention rates vary significantly by category — gaming apps typically see higher D1 but steeper drop-off than utility apps. Check benchmark reports for your specific category rather than using a single universal number. What matters is establishing your baseline so you can measure the impact of changes.
Push your first update within two weeks of launch. An update signals to the stores that the app is actively maintained. It also gives you a reason to re-engage lapsed users with a push notification ("We just shipped [specific improvement] you asked for") and an opportunity to fix the friction points your early users surfaced.
Audit your paid campaigns by Day 7. By this point you have enough install data to see which ad sets are driving users who actually retain vs. users who churn in the first session. Pause the latter. Double down on the former. Cost-per-install is not the metric that matters — cost-per-retained-user is.

FAQ
How long does App Store review take?
Apple's review typically takes 1–3 business days for standard submissions. Expedited reviews are available if you have a time-sensitive bug fix, but don't count on them for a launch date. Google Play's review is generally faster — often under 24 hours — but both stores can reject for metadata, content policy, or technical issues, which resets your timeline. Submit early.
When should I start building my waitlist?
Approximately 8–12 weeks before launch. Earlier than that and you'll lose email subscribers to churn before you send them anything. Later than that and you don't have enough runway to build a list worth having. A few hundred engaged subscribers is more valuable than a thousand cold ones.
Do I need a PR agency for an app launch?
For most early-stage apps, no. A PR agency that specializes in app launches makes sense once you have a meaningful user base or a genuinely novel story. Before that, targeted outreach to niche newsletters, podcast hosts, and micro-influencers in your category will generate more relevant installs at a fraction of the cost.
What's the right launch day UA budget?
There's no universal answer, but in our engagements, launching with too little daily budget is a real mistake — underfunded campaigns can't exit the learning phase on paid platforms, which means your CPI data is unreliable. A practical floor for Apple Search Ads or Meta is typically enough daily spend to generate 30–50 installs per day per ad set. Start there, validate, and scale what's working.
Should I launch on iOS and Android simultaneously?
Not always. If your team has limited resources for monitoring and responding to early feedback, launching iOS first and Android 2–4 weeks later lets you apply lessons from the first wave before doubling your surface area. The tradeoff is that Android users who found you in the pre-launch window may go cold. There's no universally right answer — it depends on where your target users live and your team's capacity.
How do I handle negative reviews in the first 30 days?
Respond to every 1-star and 2-star review within 48 hours, publicly, with a specific response — not a generic "sorry you had this experience." Acknowledge the issue, say what you're doing about it, and invite them to contact support directly. This practice signals to prospective users reading the reviews that the team is responsive, and in some cases, users will update their rating after a genuine response.
Ninety days of deliberate execution — before and after launch — is what separates apps that build lasting traction from apps that spike and disappear.
