FREE FOR EVERYONE
Round timer
PRESS START
3:00
Your music keeps playing and the bell rings over it. Keep this screen open — the screen stays awake while the timer runs.
Pause and play from your lock screen or media controls. Space bar = pause/play.
ROUND LENGTH
Total workout: 23:00. "Ding ding" starts and ends each round, a long ring finishes the workout, and three claps warn you with 10 seconds left.
ADD TO YOUR HOME SCREEN
Open the timer like an app, one tap from your phone's home screen.
In your browser menu (⋮), tap "Add to Home screen" or "Install app".
Tip: turn your ringer/silent switch on and volume up. Closing the app completely stops the timer.
