HIIT Workout: Interval Timer

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 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
