Tabata timer

A classic interval timer.

Settings

• Get-ready seconds before the first round (0 to skip).
• Work seconds and rest seconds per round.
• Rounds.
• Beeps: a short beep for the last seconds of each phase and a longer one at each change.

Using it

Start, Pause and Reset. The background changes colour for each phase (get ready, work, rest, done) and the tile shows the current round and the time left. The defaults are the classic 20 seconds on, 10 off, 8 rounds.

Beeps are played by your browser, so click Start at least once (browsers only allow sound after a click).
