Frequently asked questions

Why is twenty minutes a common nap length?
A nap of around 20 minutes keeps you in lighter sleep, so you wake refreshed rather than groggy — the disorientation from longer naps comes from waking mid-deep-sleep. Some people drink a coffee just before (a "coffee nap"), since caffeine takes effect around the 20-minute mark.
Is this different from a Pomodoro?
A Pomodoro is a specific 25-minute work block paired with a 5-minute break. Twenty minutes is just a plain countdown — handy for a focused sprint, a podcast segment, or a nap. For the full work/rest cycle, use the Pomodoro timer.

This timer keeps the exact time even if you switch tabs. If this tab or your browser closes, nothing can alert you at the exact finish time — there's no server behind this, by design. Come back any time and we'll tell you honestly how long ago it ended.
