Dia Key

Limit screen time on iPhone — lock distracting apps on a schedule and unlock only after your daily gratitude entry.

Dia Key is a free app lock for iPhone that helps you take control of screen time. Use the built-in locker to set scheduled lockouts — your chosen apps stay blocked until you write a short gratitude entry. Private by design: your journal lives on your device or in iCloud, with no third-party services.
