Frequently asked questions

Why 25 minutes specifically?
It is the work interval from the Pomodoro Technique — long enough to get properly into a task, short enough that committing to it does not feel daunting. After each 25-minute block you take a 5-minute break.
How is this different from the Pomodoro timer?
This is a single 25-minute countdown. The Pomodoro timer automatically cycles 25 minutes of work with 5-minute breaks across several rounds, with distinct sounds for each phase. Use that one if you want the full technique without resetting manually.

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.
