Custom duration
This 1 hour timer counts down from timestamps on your device clock, so it stays exact while you switch tabs, lock your phone or keep working elsewhere. Press Start and the large display counts down to zero with a progress bar showing how much is left.
Useful for exam practice, long workouts, deep work and slow cooking steps. Pause freezes the remaining time, Reset returns to the full 1 hour, and the +1 minute button extends a running countdown without starting over.
