Interval Timer
Set work, rest and rounds. The Timer beeps at every switch so you can keep your eyes off the screen.
How to use the Interval Timer
- Set work time, rest time and number of rounds (Tabata is 20 s work, 10 s rest, 8 rounds).
- Press Start. You get a 10-second get-ready countdown.
- Work and rest phases change color and beep at every switch.
- Go full screen so you can see it from across the room.
Interval training alternates hard effort with rest. This Timer handles HIIT, Tabata, EMOM-style circuits, stretching routines and even study intervals.
