Most mobile launches fail not because the product is broken, but because the launch is. The week before App Store / Play Store submission is when avoidable problems compound: missing analytics, broken deep links, untested edge devices, unprepared support team. This is the checklist we run at Schedars in the final 2 weeks before every mobile launch.

TL;DR

Two weeks before launch: full QA pass on real devices, store metadata + screenshots ready, analytics wired and validated, monitoring + crash reporting live, onboarding flow polished. One week before: TestFlight / Internal Testing build + 20-user closed beta, store assets uploaded, support docs ready. Launch day: phased rollout, monitor first 4 hours actively, hold a Slack war room.

Two weeks before launch

QA on real devices, not simulators

Simulators miss biometric failures, low-RAM device behavior, real network conditions, and platform-specific keyboard quirks. We test on at least: iPhone SE 3 (small screen + low-RAM proxy), iPhone 15 Pro (latest mainstream), iPad mini (small tablet), one mid-tier Android (Pixel 7a or similar), and one budget Android (Galaxy A14). Each device gets a 60-min smoke pass through the top 5 user flows.

Store metadata complete and reviewed

  • App name (30 chars) — descriptive + branded
  • Subtitle (30 chars on iOS) — value prop
  • Description (4000 chars) — paragraphs not walls; first 2 lines matter most for conversion
  • Keywords (100 chars on iOS) — research with App Store search hints
  • Screenshots (6 per device class, with overlays explaining the value)
  • Preview video (15-30s) — optional but boosts conversion 20%+
  • Privacy nutrition label (iOS) and Data Safety section (Android) — accurate, audit by hand

Analytics wired and validated

Wire your analytics in week N-2, not in week N. The five events you must track from launch: app_open, signup, activation (first meaningful action), purchase, churn-signal (X days inactive). Validate by triggering each in dev and confirming it lands in your analytics dashboard. PostHog, Mixpanel, and Amplitude all work — pick one and instrument once.

Monitoring + crash reporting live

Sentry on both platforms with proper symbol upload. Alert on crash rate above 1% or any new crash type. Set up an "ops" channel in Slack/Discord for crash alerts. Don’t skip dSYM upload on iOS — symbolicated crashes are 10x more useful than raw stack traces.

One week before launch

TestFlight / Internal Testing closed beta

20-50 hand-picked beta users get a build 5–7 days before public launch. Their job: complete onboarding, use the app for 3 days, report anything that surprised them. Daily standup with the team to triage. Anything below "minor cosmetic" gets fixed before public launch.

Store submission and review prep

Submit 5–7 days before public launch. iOS Review averages 24–48 hours but you want buffer for rejections. Common reasons for first-submission rejection: missing privacy nutrition labels, broken demo account, App Tracking Transparency prompt without context, ambiguous in-app purchase descriptions. Have a fallback plan: a "Soft Launch" backup date 7 days after the announced public launch.

Support team ready

  • FAQ doc covering the top 15 anticipated questions
  • Support email with autoresponder ("we read every message, expect a reply within 24h")
  • In-app help link to a public knowledge base or chat
  • Support team has access to admin tools to look up users, reset passwords, refund purchases
  • Pre-written response templates for the top 5 issues (login problems, purchase issues, data sync, crashes, refunds)

Launch day

  • Phased rollout on Android (start at 5% → 25% → 50% → 100% over 48 hours) — easy to halt if a crash surfaces
  • iOS launches all-at-once — but you can pull back via Phased Release in App Store Connect
  • Active monitoring for the first 4 hours: crash rate, server load, signup conversion
  • Slack war room: dev + design + support + PM all online and reachable
  • Pre-written social posts and press releases ready to fire on confirmation that the app is live
  • Don’t launch on Friday or before a holiday — fewer engineers available to respond to issues

Post-launch (first 7 days)

First 7 days set the trajectory of reviews and rankings. Daily review of: app store reviews (respond within 24h), crash rate, conversion funnel (signup → activation → purchase), top user complaints. Push at least one bug-fix release in the first week — App Stores reward responsiveness with better placement.

What we ship at Schedars

Our last 5 mobile launches (3 iOS, 2 cross-platform) all hit App Store featured-section placements within the first month. The pattern that works: a closed beta with 20+ real users for 7 days, a Tuesday launch with the team in war-room mode for 4 hours, and a follow-up patch within the first 7 days. Crash rate at week 1 has averaged 0.4% across these launches; that’s the bar to hit.

Bottom line

Launch is not a moment — it’s the final 2-week phase of the project. Teams that treat it as "we’ll figure it out when we ship" get hit by avoidable problems on day one. Teams that run a checklist ship cleanly and recover faster from the inevitable surprises.
