Keeps time accurately
The timer is based on the real clock rather than counting ticks, so it stays accurate even if you switch tabs or your computer is busy. The remaining time also appears in the browser tab title.

Work for 25 minutes, take a 5-minute break, and repeat. After four rounds, take a longer break. Use the 25 and 5 minute presets to get started.
