The App Launch Health‑Check: A 12‑Point Preflight That Prevents Post‑Release Rework

Metadata mismatches are one of the fastest ways to get delayed. Reviewers compare the shipped binary to your store listing — screenshots, feature claims, and privacy links must match what the app actually does. Open App Store Connect and Google Play Console and verify the live values against the build you're sending.

Sanity checks to do now: ensure your Privacy Policy URL resolves, Support URL is live, the primary language is correct, and there are no placeholder phrases (e.g., "lorem" or "coming soon") in promotional text or descriptions. Screenshots must be device captures of the actual app screens you ship; avoid marketing renders that reviewers can’t reproduce.

Small packaging errors derail reviews. Use deterministic, final filenames and verify your upload artifacts match store requirements — correct bundle identifiers, versionCode / CFBundleVersion, and no leftover debug symbols that expose test credentials or staging endpoints.

Verify every visual asset against platform specs: exact screenshot sizes for each device type, app icons at required resolutions, and app previews where used. App Store Connect will scale images but scaled assets sometimes trigger reviewer flags if composition differs between screenshots and the shipped UI.

If your monitoring isn’t receiving events from the first users, you’ll be blind after launch. Confirm crash reporting (Crashlytics, Sentry, Bugsnag or similar) is initialized on cold start and that network traffic for telemetry is allowed in release builds.

Do a controlled, synthetic crash in the release‑equivalent build to ensure the back end receives a report, and verify session/startup events flow through your analytics pipeline. That short verification saves days spent chasing silent failures and regressions post‑release.

Apple and Google explicitly flag apps that request permissions without context or that hide the privacy policy. Provide a clear purpose string for any permission and make sure the policy is reachable both from your listing and inside the app.

If your app requires reviewer credentials, provide a stable demo account (username / password), test credit card (or sandbox) info, or detailed reproduction steps in the App Review Notes. Without this, reviewers often return a rejection citing inability to access core flows.

Billing and subscription misconfigurations produce painful manual reviews. Ensure in‑app purchases are created in the store consoles, their product IDs match what the app requests, and promotional metadata (titles, screenshots) is set.

Test the full purchase flow in sandbox/internal test tracks. For subscriptions, verify grace periods, entitlement checks, and the UI fallback when purchases are not available. Missing billing metadata leads to rejections that always mean re-upload and re‑review.
