Background tabs or sleeping devices may delay sounds and updates. Automatic repeat catches up elapsed cycles and the current phase when you return, without a burst of missed alarms. Reloading resets the timer; device clock changes affect time remaining.
What this tool explores
Run focus or breaks separately, or alternate them, and track completed sessions.
Step by step
- Choose focus only, break only or focus + break, then set each duration in seconds or minutes.
- Choose automatic repeat and a completion sound. Preview the approximately three-second alert.
- Start, pause and resume as needed. Turn automatic repeat off to stop after the current session.
What to look for in these results
Focus supports 1 second–180 minutes; breaks support 1 second–60 minutes. Choose four sounds or no sound. Automatic repeat follows scheduled deadlines. After background throttling or device sleep, it catches up elapsed cycles and the current phase without replaying every missed alert. Reloading resets the timer.
