What is Focus timer?

The focus timer stores a target end time in this browser, so background tabs and refreshes do not make it drift. Notifications, sounds, sessions, and 30-day statistics remain local to the device.

How to use it

  1. Set focus and break durations.
  2. Optionally enable notifications, then start, pause, or reset.
  3. Review daily focus time in local statistics.

Capabilities

  • Target-timestamp timing
  • Refresh recovery
  • Notifications, sound, and 30-day stats

Limits

  • Current browser only
  • Notifications require HTTPS and permission
  • No cross-device sync
