Make every second count with Interval Timer — a clean, powerful HIIT and Tabata timer built for your workouts. Set your prep, work and rest intervals, choose your rounds, and let the app guide you through every session so you can focus entirely on training. From high-intensity interval training and Tabata to circuit work, boxing, running and yoga, Interval Timer adapts to whatever you do. It's just as useful away from the gym, too — use it as a focus timer to power through work in concentrated bursts. WHY YOU'LL LOVE INTERVAL TIMER • Fully customizable — set preparation, work and rest times to the second. • Rounds & sets — choose exactly how many intervals per session. • Clear audio cues — turn sounds on or off to know when to push and when to rest. • Save your timers — store your favorite routines and start them in one tap. • Distraction-free — a minimalist design that's easy to read mid-workout. • Works offline — train anywhere, with no internet connection. • Light & dark themes — comfortable in any environment. • 70+ languages — built for athletes worldwide. GREAT FOR EVERY WORKOUT • HIIT and Tabata sessions. • CrossFit, circuit training and bootcamps. • Boxing, MMA and heavy-bag rounds. • Running, sprints and interval cardio. • Yoga, stretching and mobility flows. • Focused work sprints using the Pomodoro technique. HOW IT WORKS 1. Set your prep, work, rest and number of rounds. 2. Save the timer or start it right away. 3. Follow the cues — work hard, rest smart, repeat. WHY INTERVAL TRAINING WORKS Short bursts of intense effort followed by recovery are one of the most efficient ways to train. Interval workouts build endurance and save time — but only if your timing is precise. Interval Timer keeps you honest, counting every work and rest period so you get the full benefit of every session. PERFECT FOR • Gym-goers and home-workout fans. • Runners, boxers and CrossFit athletes. • Anyone short on time who wants maximum results. • Focused workers timing productive sprints. Whether you're chasing a new personal best or just trying to move more, Interval Timer brings structure, rhythm and intensity to your training. Set it once, save it, and let it push you toward your goals — one perfectly timed interval at a time. FOCUS ON TRAINING, NOT THE CLOCK The hardest part of interval training is keeping track of time while you're gasping for breath. Interval Timer takes that off your plate completely. Set your session once, hit start, and let clear audio cues tell you exactly when to explode into work and when to recover — no glancing at a watch, no losing count, no broken rhythm. BUILD THE SESSION YOU WANT Quick Tabata blast or a long circuit, equal work and rest or lopsided intervals, two rounds or twenty — it's all yours to shape. Dial in your preparation time so you're ready before the first round, save the routines you love, and launch them in a single tap next time. MORE THAN A GYM TOOL Interval training isn't just for athletes. Use timed intervals to make housework fly by, to structure focused study or deep-work sprints, or to add rhythm to stretching and breathing exercises. Anywhere a little structure helps, Interval Timer is ready. Interval timer for HIIT and Tabata: a workout and exercise round timer with custom work, rest and prep intervals, sets and audio cues for the gym, cardio, boxing, CrossFit, circuit training and running.

Verdict

The call

HIIT Workout's advantage is iOS requirement (13.0 vs 15.6). On price, rating, in-app purchases and monetization model there is nothing between them.
