Interval Timer: HIIT & Tabata - Google Play

Interval Timer is a simple, colorful workout timer for HIIT, Tabata, circuit training and any workout built from rounds of work and rest. It is an interval timer you can actually read mid-set: no account and no sign-up needed.

Set your series, train time and rest time, then press start. Big numbers and a full-screen color for every phase mean you can read the timer from across the room, mid-burpee, without reaching for your glasses.

BUILD ANY WORKOUT
- Repeat blocks you can nest, for rounds within rounds
- Custom phases, each with its own name, color, sound and vibration
- Drag and drop to reorder phases, blocks and saved timers
- Save workouts as presets and start them in one tap
- Share a timer with a friend through a link

TRAIN WITH THE SCREEN OFF
A colored notification keeps counting while the phone is in your pocket: current phase, time remaining, and quick pause, stop and skip controls, with a heads-up alert at every phase change. Nothing stops when the screen does.

A REAL WEAR OS APP
Not a remote control. Build and run interval timers on the watch itself, with an ongoing activity on your watch face and a vibration at every phase change, so you can train with your phone put away. Presets sync between phone and watch.

ONE TIMER, EVERY SPORT
As a HIIT timer it counts work and rest for you so you never check the clock mid-round. As a Tabata timer the classic 20/10 for eight rounds is two taps away, and you can save it as a preset. As a boxing round timer it calls three-minute rounds with a minute between them, and warns you before the bell. As a gym timer it keeps your rest between sets honest instead of letting a set turn into a scroll. As a circuit timer it walks a whole station-by-station circuit with a named phase for each move. As a running interval timer it counts your sprint and recovery intervals out loud so you can keep your eyes up.

QUESTIONS PEOPLE ASK
Does the interval timer keep running with the screen off? Yes. The workout keeps counting in a notification, and alerts still fire at every phase change.
Can I build a Tabata timer? Yes. Set 20 seconds work, 10 seconds rest, 8 sections, and save it.
Can I use it as a round timer for boxing? Yes. Set the round and rest lengths you box, and give each phase its own sound.
Does it work on my watch? Yes. There is a full Wear OS app that builds and runs timers on the watch itself.
Do I need an account? No. Everything works without one. With Pro you can sign in to back up your timers and pick them up on your other devices.

FREE TO START, PRO WHEN YOU WANT MORE
The timer is free to use. Interval Timer Pro removes the ads, saves unlimited timers (the free plan keeps up to 3), and backs up your saved timers, settings and personal sounds to every device you use. It also supports an independent developer.

An account is optional. Nothing collected about your workouts.
