20 Minute Timer

What Is a 20-Minute Timer Used For?

A 20 minute timer is a sweet spot between a quick task and a full Pomodoro. It's long enough for a workout, a chapter of a book or a set of practice questions, and short enough that you won't drift. Press Start, keep the tab open, and the alarm tells you when 20 minutes are up.

Workout or yoga

A 20 minute session is enough for a full HIIT circuit, a run or a yoga flow.

💡 The 20-20-20 eye rule

If you work at a screen, a common tip from eye-care organisations is the 20-20-20 rule: every 20 minutes, look at something about 20 feet (6 metres) away for 20 seconds. Run this timer, and when it rings, look out of a window before you start the next block.
