Interval Timer | HIIT Training

Easy to use interval timer for Android and Wear OS.

Set the number of series, train time and rest time, with a colorful interface that makes the current state of the timer easy to read at a glance.

Build your own workouts:

- Repeat blocks you can nest to create rounds within rounds

- Custom phases, each with its own name, color, sound and vibration

- Drag and drop to reorder phases and blocks

- Save workouts as presets and reuse them anytime

- Presets sync between your phone and your Wear OS watch

Keep training with the screen off: a colored notification (and Wear ongoing activity) shows the current phase, counts down, and gives you quick pause, stop and skip controls, plus a heads-up alert on each phase change.

Perfect for any of your training activities:

- HIIT Training

- Tabata

- Circuit training

- Pomodoro

...and more.
