HIITimer: Interval Timer

Circuit rounds on Apple Watch

Free · In-App Purchases

The interval timer that keeps going when you lock your phone. A number you can read from across the room. Cues you hear through your music. No subscription. READ THE COUNTDOWN FROM ACROSS THE ROOM The whole screen is the signal. Orange while you work, blue while you rest. The screen stays awake for the whole workout, so you can prop the phone against the rack or on the treadmill. On iPad, the countdown fills the entire screen. HEAR IT THROUGH YOUR MUSIC Put the phone in your pocket and let the sound lead. Five seconds before the start, you get counted in. Two rising tones warn you the phase is about to end, and four beats take you into the switch: three, two, one, go. Your music keeps playing – it isn't turned down or paused. You set the volume of the cues yourself: three levels, or off. IT ONLY STOPS WHEN YOU WANT IT TO Lock the phone and put it away. The countdown runs to the last interval, and the Lock Screen shows what's left. Need a break? Tap pause, and keep going when you're ready. READY IN SECONDS Work, rest and number of intervals on a single screen, with the start button always in view – no scrolling with sweaty fingers. Adjust in five-second steps, or pick one of the built-in presets. TRAIN FOR FREE Up to ten intervals, Tabata, 30/15 and 4×4. After every workout you see how many weeks in a row you've trained. You don't need an account, there are no ads, and nothing leaves your phone. Works offline, in 16 languages. PRO Pro is a one-time purchase. No subscription, nothing to cancel. Build your own workout With the Workout builder, every interval and every rest gets its own length. Pyramids that climb and come back down, ladders that go one way, or every interval set up on its own. Name your intervals – Burpees, Rowing – so you always know what's coming. Leave the phone where it is Set up the workout on your phone and let Apple Watch run it on its own – with music, if you like. You feel every phase change on your wrist. Glance at the watch, and your heart rate is there. Apple Watch runs only one workout at a time, so neither the Workout app nor other workout apps can run a workout alongside HIITimer – and you won't need to. The Digital Crown turns the cue volume up and down. When you're done, the workout is in Health, with your heart rate and active energy. Requires watchOS 11. See your heart rate while you train With a heart rate sensor, your heart rate sits on your phone's screen next to the countdown, even while another training app is using the same sensor. You decide whether the workout, heart rate included, is saved to Health, so it doesn't end up there twice. Everything in Pro • Up to 99 intervals and 20 sets • Workout builder: pyramids, ladders and circuit training • Every preset: EMOM, 30/30, 40/20 and multi-set versions • Save your own presets • The Apple Watch app • Heart rate from a sensor or Apple Watch • Copy the workout with RPE to your training log Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://hallvardfanebust-dev.github.io/hiitimer/privacy.html

Ratings & Reviews

  • This app has not received enough ratings or reviews to display an overview.

• See your heart rate while you train, from a sensor or Apple Watch (Pro). • Pause: stop the workout and keep going when you're ready. • "Advanced workout" is now the Workout builder, and intervals can have names, like Burpees or Rowing. • See how many weeks in a row you've trained. • New built-in workout in the free version: 30/15. • The report tells you more: the rest, the names of your intervals, and how far you got if you stopped early. • A new, calmer start screen. • Built for iPad, and adapted for iPhone Duo.
