About this app
HIIT Timer is a reliable interval timer for HIIT workouts, Tabata, gym sessions, boxing rounds and run/walk training. Use it as a workout timer for home circuits, lifting, track sessions and classes.
Use it as a HIIT timer, Tabata timer, gym rest timer, EMOM timer, boxing round timer or running interval timer—for circuit training, lifting, sprints, hill intervals, run/walk sessions, martial arts, home workouts and group classes.
Build custom work/rest intervals in seconds, add exercise names and weights, and chain multiple workouts into one training session. Choose a starter, tap start and follow clear audio, vibration and on-screen cues. No account or internet connection is required for training.
Built for the way people actually train:
• CUSTOM INTERVALS: Set work, rest, rounds, sets, warm-up and recovery between sets. Save a workout once and reuse it.
• TABATA TIMER: Start with Classic Tabata at 20 seconds work, 10 seconds rest and 8 rounds, or customise the intervals.
• GYM REST TIMER: Run a simple rest countdown between lifting sets, with a clear alert when it is time to start again.
• EMOM TIMER: Train every minute on the minute with minute-by-minute cues.
• BOXING TIMER: Set round and rest lengths with distinct bell-style cues.
• RUNNING INTERVAL TIMER: Keep your phone in your pocket while audio and vibration signal each change.
• SCREEN-OFF RELIABILITY: The timer continues while the screen is locked. Use the notification to check progress and control the timer without unlocking.
• LOUD, ADJUSTABLE CUES: Control cue volume and vibration, add a countdown or halfway chime, and calibrate for Bluetooth earbud delay.
• WORKS WITH YOUR MUSIC: Choose whether cues briefly duck your music, pause it or leave it playing.
• EASY TO READ: Large countdown digits and distinct work/rest colours stay readable across the gym.
• COMPLETE SESSIONS: Chain Tabata, intervals, EMOM, boxing rounds, rest timers and labelled exercises into one planned session.
• HISTORY AND STREAKS: Review training by day, month, year or All, with workout summaries and streaks stored on your device.
• PRIVATE BY DESIGN: No account, no ads, no analytics and no cloud workout storage.
Free includes every shipped timer mode, all cue controls, on-device history and one saved session with as many workouts as you like. Pro unlocks unlimited saved sessions through a one-time purchase, monthly subscription or yearly subscription.
HIIT Timer is an interval timer, not a coach or medical device. It does not provide medical, health or fitness advice. Exercise carries a risk of injury. Seek appropriate medical advice before beginning a programme and stop if you feel unwell. Cue delivery depends on your device's power, volume and Do Not Disturb settings.
