About the 20 Minute Timer
Twenty minutes is long enough for a full short workout, a homework block or a dish in the oven.

The 20 20 20 rule for your eyes
Eye doctors suggest the 20 20 20 rule for screen work: every twenty minutes, look at something about twenty feet away for twenty seconds. Run this timer while you work and use the alarm as your reminder to look away.
Twenty minute workouts
Circuit and bodyweight routines often fit into twenty minutes. Use full screen so you can read the time from the floor, and pair it with our 30 second timer if your routine has short rounds.
Quick ideas

Press Start. The orange ring shrinks as time passes and the time left also shows in your browser tab, so you can see it while you work in another tab. Press Pause to stop and Resume to carry on. When it reaches zero, the alarm plays and the numbers flash.
