Frequently asked questions

Does it keep counting in a background tab? expand_more
Yes. Time is computed from the clock, not by counting ticks, so it is right when you come back.
What is the Pomodoro technique? expand_more
25 minutes of work followed by a 5-minute break, with a longer break after four rounds.
Does it alert me when time is up? expand_more
Yes, with a short run of beeps when the time ends, so keep your volume up.
Is anything stored? expand_more
No. Everything runs on your device and nothing is sent.
