Read your workout from across the room.
The whole screen takes the color of what you should be doing right now. Ten regimes from Tabata to Norwegian 4ร4, your own numbers, haptics on your wrist, and everything stays on your device. In testing.


Built to be glanced at, not read.
You do not read a timer mid-burpee. The screen changes color, the numbers fill it, and it drains like a shot clock.
Read it across the room
The whole screen takes the color of the current interval, with a next-up preview and the time left.
Ten regimes
Tabata, EMOM, AMRAP, ladder, pyramid, Norwegian 4ร4, 7-minute, circuit, 30/30 and custom HIIT, each with its own shape.
Make it yours
Edit work, rest, rounds, get-ready and cool-down with a live preview. Light, dark or follow the system.
On your wrist
Apple Watch and Wear OS apps with distinct haptic patterns for the countdown, go, ease off and done.
Honest history
Records what you actually did: pauses, skips and rounds finished. Weekly goal and streak.
Private by design
No account, no ads, no tracking. Everything stays on your device, and you can delete it any time.
The screen is the signal.
Yellow to get ready, red to work, blue to rest, teal to cool down. The bright area drains from the top like a shot clock, and the last three seconds beat once each.
- Next-up preview and total time left
- Skip forward or back; skipped time is not counted
- Sound cues are rendered into one audio track so they stay on schedule with the screen off

Take a look around.
