Mobile

Lifecycle Awareness

• App can be killed anytime in background—save state before backgrounding
• Restore state on return—user expects to continue where they left off
• Handle low memory warnings—release caches, non-essential resources
• Background tasks have time limits—complete or request extension

Permissions

• Ask in context, not at launch—explain why when requesting
• Degrade gracefully if denied—app should still work with reduced features
• Don't ask for unnecessary permissions—users notice and distrust
• Re-request after demonstrating value—not immediately after denial

Offline First
