Run more timers

Add as many timers as you need. Each one rings on its own.

Focused work sprints (the Pomodoro method uses 25 minutes), workouts and cooking.

How do I set a timer for 15 minutes?

Press Start. The timer counts down 15 minutes and plays your chosen sound at zero. You can pause or reset it at any point.

How many seconds are in 15 minutes?

15 minutes is 900 seconds, or 15 minutes.

Does the timer keep running if I switch tabs?

Yes. The timer tracks the finish time, so it stays accurate in a background tab. Allow notifications to get an alert when it ends.
