HIIT Workouts
Interval timer you can feel
Free · Designed for iPhone. Not verified for macOS.
Eyes-free interval training — let the haptics run your workout.
HIIT Workouts is a no-fuss high-intensity interval timer built for Apple Watch — with an iPhone companion that's a full partner, not just a second screen. Set your total session length and work/rest splits, then put your wrist down and go: pronounced haptic cues call every transition so you never have to look at the screen.
ON YOUR WATCH
- Wall-clock-accurate interval timing, anchored so cues never drift
- Strong, escalating haptics: a build-up countdown into each work and rest, a bigger jolt for the final interval, and a celebratory finish
- Live heart rate and a workout saved to the Health app
- Keeps running wrist-down for the whole session
- A watch-face complication to launch straight into the app
ON YOUR IPHONE
- Start, pause, resume, or end a session from your phone — the watch follows in real time and records the real workout
- Live countdown in big type: ring, phase, and set count, anchored to the same clock so both devices stay in lockstep
- Live heart rate and active calories during the workout, with an average heart rate and calorie summary at the finish
- Workout history straight from Health: duration, calories, and average heart rate for every HIIT session
- Works with HIIT workouts logged by any app, not just this one
START ON EITHER DEVICE
Begin on your watch or your phone — whichever you reach first. Starting on one wakes and syncs the other, and if a device is closed or crashes mid-session, you can rejoin the workout already in progress.
Designed watch-first for intervals, circuits, Tabata, and any work/rest routine.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
The iPhone and Apple Watch are now equal partners. Start, pause, resume, or end a session from either device and the other follows the same countdown in real time — the watch still records the real workout and is woken from your phone if it isn't already running.
Start a workout right from your iPhone — it opens HIIT on your watch so the countdown and haptics are ready on your wrist.
Rejoin a workout in progress. If a device is closed or crashes mid-session, the start screen offers to drop you back into the live countdown.
Your iPhone now shows live heart rate and active calories during a workout, plus an average-heart-rate and calorie summary at the finish.
A new watch-face complication launches HIIT in a single tap.
Custom session length and work/rest intervals now sync between your devices, so both start screens stay in step.
Refreshed start and welcome screens, rounded typography throughout the watch app, and a new flame app icon.
