Plan for errors, not just the happy path
List the main action, loading state, empty state, error, retry, and recovery after the app returns from the background. For an upload or submission, decide how to prevent duplicates and how the person knows whether the action succeeded.
Decide how the app works offline
Decide which information remains available without a network and whether edits can be queued. Define synchronization, conflicts, and sign-out behavior. Offline support affects storage and security, so decide on it early. It’s hard to add at the end.
Plan the whole login lifecycle
Plan secure token storage, expiry, refresh failure, account changes, and removal of local records at sign-out. Review deep links, notifications, and shared-device behavior. Keep provider secrets and privileged operations on the server.
Test on real devices
Check supported OS versions and real screen sizes, keyboard and safe-area behavior, larger text, screen-reader labels, reduced motion, cold startup, and long lists. Simulators are fine for layout. Use real devices to check speed and hardware features.
Agree who handles the stores
Document who owns signing, developer accounts, privacy disclosures, screenshots, release notes, review responses, and staged rollout. Check the framework support policy and each dependency before upgrading. Apple and Google still make the final call on approval.
