An interval timer for Tabata, HIIT, EMOM and circuits
TimerHub’s interval timer runs any work-and-rest workout: Tabata (8 rounds of 20 seconds on, 10 off), HIIT (45 on, 15 off), EMOM (a new set every minute on the minute), circuits with named exercises, or your own custom intervals. It counts against the real clock, so every round stays exact in a background tab.
Each phase has its own colour and its own sound. Work floods the screen sunrise-orange with a bright rising tone, rest turns it dusk-blue with a low falling one, and three ticks count you into every change. Turn on Voice and it tells you where you are: “Rest. Round 3 of 8.”
Heavy numbers fill the fullscreen, and the colour says work or rest before you read a digit.
Three ticks into every change, a rising work call, a falling rest call and a triple at the end.
No ads, no signup, no pop-ups. The screen stays awake while it runs.
How to use the interval timer
- Press Start, or tap a programmeTabata, HIIT, EMOM, Intervals and Circuit start the moment you tap them, after a 10-second get-ready. Focus moves to Pause, so Space or Enter pauses it.
- Tune it with the big − and +Get ready, work, rest and rounds — or type a time like 1:30. A circuit names each exercise with its own time. Your changes are kept on this device as Custom.
- Prop up your phone and go fullscreenWork floods the screen warm and rest turns it cool, with “Work · 3/8” and “Next · Rest 0:10” as big as the room needs. Pause dims but never disappears.
