Launching a mobile app is a 50-step process where skipping any one step can cost you weeks. We have launched multiple apps through Apple and Google's review processes. Here is the complete checklist, in order.
Beta Testing (4-6 Weeks Before Launch)
TestFlight (iOS) and Google Play Internal Testing are your beta platforms. Both are free and integrated with the stores.
Recruit 20-50 beta testers. Mix of target users and non technical people. Technical testers find bugs. Non technical testers find UX problems. Both matter.
Crash reporting from day one. Set up Sentry or Crashlytics before your first beta build. Every crash should create a ticket with the stack trace, device info, and reproduction steps. Target: less than 1% crash rate before launch.
Analytics integration. Instrument your core user flows with Mixpanel, Amplitude, or PostHog. You need to know: which features are used, where users drop off, session duration, and retention. If you cannot measure it before launch, you cannot improve it after.
Performance benchmarks. App launch time under 2 seconds. Screen transitions under 300ms. API calls under 1 second. Memory usage under 200MB. Battery drain within normal bounds. Test on the oldest supported devices, not just the latest flagship.
App Store Preparation (2-3 Weeks Before Launch)
App Store screenshots. 6.7-inch (iPhone 15 Pro Max) and 6.1-inch (iPhone 15) sizes are required for iOS. Use tools like Fastlane to automate screenshot generation across locales. Tip: your first screenshot is the most important, it should show your app's core value, not a splash screen.
App Store description. First three lines are visible without expanding, put your strongest value proposition there. Include relevant keywords naturally. Do not keyword stuff, Apple rejects apps for this.
Privacy policy and terms of service. Required by both stores. Must be hosted at a public URL. Apple checks that your privacy policy accurately describes the data your app collects. Discrepancies cause rejection.
App Store review guidelines. Read Apple's Human Interface Guidelines and Review Guidelines end to end. Common rejection reasons: incomplete metadata, placeholder content, broken links, login requirements without a demo account, and in app purchase policy violations. Our App Store approval guide covers the most common gotchas.
Demo account. Apple reviewers need to test your app. Provide login credentials in the review notes that access real functionality. Reviewers spend 5-10 minutes, make sure the demo account shows your app at its best.
Technical Pre Launch
Remove all debug code. console.log statements, debug menus, test API endpoints, and development flags. A single visible debug element causes rejection.
Error handling for offline states. Every screen should gracefully handle no network connectivity. Show appropriate messaging, cache what you can, and never show a blank screen or unhandled error.
Deep linking. Set up universal links (iOS) and app links (Android) for your key content. This lets marketing campaigns, emails, and social posts link directly into your app. Configure these before launch, retroactively adding deep linking is painful.
Push notification permissions. Request push notification access at the right moment, not on first launch. Wait until the user has experienced your app's value, then ask with context about what notifications they will receive. Apps that ask immediately see 40-60% opt in. Apps that wait for the right moment see 70-80%.
Submission Process
Submit to Apple first. Apple's review typically takes 24-72 hours but can take up to a week. Google Play review takes hours to a day. Submit to Apple first and time your Google Play submission so both approvals land in the same window.
Version numbering. Start at 1.0.0. Semantic versioning: major.minor.patch. Apple tracks your version history, and starting at anything other than 1.0 looks odd.
Build with release configuration. This sounds obvious, but we have seen debug builds submitted to the App Store. Use your CI/CD pipeline to produce release builds automatically, human built releases are error prone.
Launch Day
Monitor everything. Watch crash rates (Sentry), API error rates, server load, and user signups in real time. The first 24 hours surface issues that testing missed because you finally have real users on diverse devices and networks.
Have a hotfix plan. If a critical bug appears on launch day, you need to ship a fix within hours, not days. For iOS, Apple offers expedited review for critical fixes. For Android, staged rollouts let you push fixes to a percentage of users first.
Do not launch on a Friday. If something breaks, you want your team available. Tuesday through Thursday are the best launch days.
Post Launch (First 30 Days)
Respond to reviews. Every 1-star review should get a response within 24 hours. Ask for specifics, offer to fix issues, and follow up. This turns detractors into advocates and shows potential users you care.
Monitor retention. Day 1 retention above 40% is good. Day 7 above 20%. Day 30 above 10%. If your numbers are significantly below these benchmarks, there is a fundamental problem with your core loop that needs fixing before spending on acquisition.
Iterate based on data. Your analytics will reveal surprises, features you thought were core going unused, unexpected workflows, and performance issues on specific devices. Ship updates every 1-2 weeks for the first month.
We launched Traderly across iOS, Android, and web simultaneously, the checklist above is what kept the launch smooth. Getting the details right saves weeks of App Store back and forth.
