Work in focused 25-minute blocks with a 5-minute break after each and a longer 15-minute break after every fourth. The timer switches phases on its own and alerts you each time; change any length to suit you.

## How to use it

1. Keep 25 / 5 / 15 or set your own lengths.
2. Press Start and work on one task until the alarm.
3. Take the break when it rings; the next focus block starts automatically (switch that off if you prefer).

## Details

- **Defaults:** 25 min focus, 5 min short break, 15 min long break

## Questions

### Does it need an account or send anything?

No. It runs in this page with your device's clock. Nothing is stored on a server.

### What is the Pomodoro Technique?

A time-management method created by Francesco Cirillo: work on one task for a fixed block (traditionally 25 minutes), take a short break, and take a longer break after four blocks.

### Should I use 25 minutes or longer?

25 minutes is the classic length and suits tasks that are hard to start. Many people use 50 / 10 for deep work. Try a few days with each and keep what you finish more with.

### Does it keep running in the background?

Yes, while the tab is open. It counts from the system clock, so it stays accurate even when the browser slows background tabs.
