Everything you need to know about the best interval timer app.
Super Interval Timer is an interval timer built for HIIT, Tabata, boxing, EMOM, circuits, strength work, and any custom interval workout. Instead of a basic countdown, you build workouts from scratch — add exercises, rest periods, and repeat rounds in any combination — then train hands-free with a background timer, lock-screen controls, and voice cues. Every feature is free to try for 14 days. Launching on Android via Google Play, with iOS on the way.
Tap CREATE NEW on the home screen to open the workout builder. Add Work blocks and name them anything (burpees, squats, sprints), add Rest blocks, and use Repeat to loop your circuit — you can even group blocks into bigger circuits. Set any duration for each block, save, and your workout appears on the home screen ready to start. Prefer not to build? Start from the ready-made presets like Classic Tabata, EMOM, or Boxing and tweak from there.
Yes — this is Super Interval Timer's core strength. The timer runs natively in the background, so it keeps perfect time with your screen locked or while you use other apps. A live notification shows your current exercise, the countdown, and your round progress, with pause and skip controls right from the lock screen. Audio cues and voice assist play over Spotify or any music app without interrupting your playlist.
Classic Tabata (20 seconds on, 10 off, 8 rounds), HIIT circuits, strength sets with rest periods, boxing rounds (3 minutes on, 1 off), EMOM workouts, sprint intervals, and warm-up or cooldown blocks — anything you can express as work, rest, and repeat. Workouts are fully custom: any exercise names, any durations, unlimited saved workouts.
You start with a 14-day free trial with full access to every feature — no account signup and no payment details needed. After the trial, a single one-time payment unlocks lifetime Pro access. No subscription, no recurring charges, no hidden fees.
Tabata is a specific type of HIIT (High-Intensity Interval Training). Classic Tabata follows a strict 20 seconds of work, 10 seconds of rest, repeated for 8 rounds (4 minutes total). HIIT is broader and can include any combination of high-intensity exercise intervals and rest periods — like 40 seconds on, 20 seconds off, or circuits with different exercises. Super Interval Timer supports both: use the Classic Tabata preset for the traditional protocol, or build your own custom HIIT circuit with any exercises, durations, and rounds you want.
Super Interval Timer is the best free interval timer and workout timer app built for athletes, gym-goers, and home workout enthusiasts. Use it as a HIIT timer, Tabata timer, exercise timer, circuit training timer, boxing round timer, rest timer, or EMOM timer. Whether you train with Tabata protocols, HIIT circuits, strength training sets, boxing rounds, or yoga flows, our custom workout builder and hands-free background timer make every session effortless. Stop fiddling with basic stopwatch apps. Build any interval workout in seconds, hit start, and let the workout timer do the rest. Launching as a free exercise timer on Google Play, with iOS on the way.
