One interval timer for HIIT, Tabata, boxing and circuits

You set work, rest, rounds and sets. SetGo Timer guides you through every session with voice announcements, haptics and color-coded phases.

HIIT timer

Alternate hard efforts with short rests, for example 40 seconds of work and 20 seconds of rest. Set the durations, rounds and sets once and save the timer.

e.g. 40 s work · 20 s rest

Tabata timer

The classic protocol: 20 seconds of work, 10 seconds of rest, 8 rounds. Set it up once, mark it as a favorite and start it in seconds.

20 s work · 10 s rest · 8 rounds

Boxing round timer

Three-minute rounds with a one-minute break, for as many rounds as you like. Voice announcements and haptic feedback mark every round, so you never have to look at the screen.

e.g. 3 min rounds · 1 min rest

Circuit training timer

Chain several exercises into one timer, each with its own work and rest times. SetGo Timer announces every exercise change.

Multiple exercises in one timer
