Repeat Timer
A timer that repeats the same duration multiple times, with an optional rest between rounds — set a round count or run forever until you stop it.

Settings are stored only in this browser. The remaining time shows in the tab title even when you’re on another tab, and time that passed while the screen was off is caught up using the real clock. Sounds are synthesized in your browser, so nothing is downloaded.

How to use
Set the length of one round and the rest between rounds. Leave rest at 0 to go straight into the next round with no gap.
Set a number of rounds, or turn on "Repeat forever" to keep going until you stop it yourself.
Click "Start" and rounds and rest periods repeat automatically. Use "Skip" to jump past the current step, or the −1m/+1m/+5m buttons to adjust the remaining time on the fly.
