About this app

Restwork is a simple, reliable interval timer and workout timer for HIIT, Tabata, EMOM, boxing rounds, run-walk intervals and bodyweight training.

START IN SECONDS
• Quick start: set work, rest and rounds, then tap Start. Your last values are remembered.
• Ready-made workouts such as Tabata and EMOM, plus a library of popular routines.
• Save your own workouts with sets, rest between sets, warm-up and cool-down.

MADE FOR REAL WORKOUTS
• Big, colour-coded numbers you can read from across the room, in portrait or landscape.
• Beeps, a 3-2-1 countdown, an optional halfway alert, vibration and spoken cues ("Work", "Rest", "Last round") in your language.
• Keeps running with the screen off or locked, and the lock screen shows the time left.
• Your music keeps playing and only dips briefly at each cue.
• Lock the screen against sweaty taps; hold to stop.

PHONES AND TABLETS
• Two-pane layout on tablets, landscape support on phones.
• Light, dark or system theme.

PRIVATE BY DESIGN
• No account and no sign-up. Your workouts stay on your device.
