Two Modes, One Tool

Switch between Countdown mode (count down from a set time) and Stopwatch mode (count up with lap tracking). Both modes support pause/resume and run in the background.

Countdown Timer

Set hours, minutes, and seconds manually or use quick preset buttons for common durations. A visual circular progress ring shows elapsed time at a glance. An audio alert plays when the countdown reaches zero.

Stopwatch with Laps

Start the stopwatch for precise timing with centisecond accuracy. Record lap times to track splits — useful for exercise intervals, cooking, or any activity that needs segment timing.

Practical Use Cases

  • Cooking — Set precise timers for recipes and baking
  • Exercise — Time intervals, rest periods, and track lap splits
  • Presentations — Keep track of time during talks and meetings
  • Study sessions — Set timed study blocks with breaks
  • Games — Use as a game timer with sound alerts
