HIIT interval timer

Read the round from across the room.

The whole screen turns red for work and pale blue for rest. Beeps and a voice call every change, so you never look down mid-set.

How it works

Set it once. Then just train.

  1. 01

    Build your workout

    Set work, rest, rounds and cycles, with a warm-up and cool-down if you want them. Or list your exercises and each round takes a name.

  2. 02

    Hear every change

    Beeps count down the last seconds, climbing in pitch into the change. A voice calls the next exercise, and Android phones buzz as well.

  3. 03

    Put the phone down

    The screen stays on while you train. If the phone does lock, the timer jumps to exactly where you should be the moment you unlock it.

What's in it

Everything a timer needs. Nothing else.

  • Named exercises

    Each round is called out by name, with its own work time if you want one.

  • Light for bright sun

    Black on white for training outside. Work stays red and rest stays blue.

  • History

    Every run is logged by day, with this-week and all-time totals.

  • Share by link

    Send a workout as a link. A friend opens it and taps Save.

  • Works offline

    After the first visit it opens with no signal, gym basements included.

  • No account

    Nothing to sign up for. Your workouts and history stay on your phone.
