What is the Interval Timer?
A simple, loud and clear timer for HIIT, Tabata, circuits, boxing rounds and stretching. Set work time, rest time, the number of rounds and sets, and the timer counts you through every interval with beeps, voice announcements and a colour-coded full-screen display (green = work, blue = rest).
It keeps the screen awake while running (on supported phones) so you can prop your phone up and train.
How to use the Interval Timer
- Pick a preset or set work, rest, rounds and sets.
- Press Start – a 10-second “get ready” countdown begins.
- Follow the colours and beeps. Pause anytime.
