Workout beeps
over any audio.

Most workout timers pause your music or video when they make a sound. This one doesn't. Keep a show, playlist or podcast playing, and clear beeps tell you when to work and when to rest.

What it does

Plays over your audio

Beeps play on top of whatever you're listening to, without stopping or lowering it.

Just three numbers

Set work time, rest time and sets. Tap a number to pick it from a wheel, or use + and −.

Hear every change

Beep-beep-beep in the last three seconds, a higher tone when work or rest begins, and a finish sound at the end. A soft click every second keeps the pace (you can turn it off).

Keeps running in the background

Lock the screen or switch apps — the timer keeps exact time and keeps beeping.

Made for glances

Huge numbers and a full-screen color change between work (lime) and rest (black).

No account, no ads, no tracking

Works offline. Your settings and presets stay on your device.
