WorkHIIT
A precision interval timer for any workout.
Built to work.
Five modes, one language.
Timer, HIIT, Circuit, EMOM, and Stopwatch all share the same glanceable clock and the same start-and-go flow. Switching formats never means relearning the app.
Cues tuned to the moment.
Work, rest, and the final countdown each get a distinct tone and paired vibration, layered over your music without pausing it. Choose from three workout completion tones we made ourselves.
A clock from the gym wall.
The seven-segment display comes straight from gym-timer hardware, in a collection of color pairs we tuned by hand; or switch to a clean Modern face, if you'd prefer. Display Mode turns the whole screen into the clock.
Your formats, saved.
Keep your go-to configurations one tap away, starting from built-in presets like Tabata and AMRAP.
Native on both platforms.
WorkHIIT is written natively for iOS and Android. Setting up a timer follows each platform's own conventions, so the app feels at home on your phone.
Set it, then forget the phone.
The screen stays awake for the whole workout, and a completion alert can reach you even with the screen locked.
Accessible throughout.
VoiceOver and TalkBack read the clock as spoken time, not digit by digit, and every control is labeled. Interface text scales with your system text size, every cue pairs a vibration with its tone, and a workout is fully followable without sound.

Free, and staying that way.
No ads, no subscriptions, no feature paywall. Everything the timer does is free. On iOS, the one purchase is cosmetic — a one-time unlock for more clock colors; on Android, there's nothing to buy at all. WorkHIIT's function isn't something we'll charge for.
