A free interval timer with no imposed structure

Build any routine, run it without touching your phone, and read it from across the room.

Build any routine

Set work and rest steps, name each one and group them into repeats. HIIT, Tabata, EMOM, AMRAP, circuits or rounds.

Run it hands free

A big countdown fills the screen. Sound and voice cues call every switch, so you never watch the clock.

Yours to keep

Everything stays on your device. No account and no sign in. Back up or share any routine as a file.

No fixed structure. Shape it exactly how you want.

Give each step a label, duration, colour, sound and voice. Group steps into a repeat block, or start from a template and adjust it.

  • Repeat blocks loop a round as many times as you need
  • Chain separate timers into one warm-up to cool-down session

Full-screen colour per step, so you know your phase at a glance.

A giant readout sits inside a progress ring, sized to read from the far side of the gym. A voice calls each step and counts you in on the last three seconds.
