A boxing-style interval round timer, stripped to what matters: set it, start it, train to the bell. The timer keeps running with your screen locked. No account, no ads, nothing tracked.
What it does
Set your round count, round length and rest — or tap a preset like Full Card (12 × 3:00).
Non-Stop mode for continuous rounds with no fixed end.
A bell at the start and end of every round; a wooden clap ten seconds before the bell.
Vibration on every cue. Plays over your music, and can dim it so the bells stand out.
Runs in the background so the bell rings with the phone locked.
