FocusLock

FocusLock is a self-commitment focus timer for studying, reading, and deep work.

When you complete a session, your current accumulated focus time grows. If you leave the app during a session and do not return within your grace period, the current accumulated focus time resets to zero. It does not block other apps at the OS level; it helps you pause before leaving by making the cost visible.

Features:
- 25, 45, and 90 minute presets
- Custom sessions from 1 to 180 minutes
- Wall-clock based countdown
- Configurable grace period
- Limited daily emergency pauses
- Current accumulated focus time
- Session history
- Daily, weekly, and monthly stats
- Local-only storage
- No ads, no analytics SDKs, no account required

FocusLock does not access contacts, SMS contents, call participants, payment data, or other app usage history. Calls and messages are handled through the grace period and emergency pause settings.
