Round Timer: HIIT & Tabata

Start workouts in a tap with GO, follow clear voice prompts, and enjoy music playing while cues sound. Live Activity, widgets, history, and Health tracking with Pro.

Stop struggling with complex timers and begin your workout in moments. Enjoy clear interval prompts, a large easy-to-see countdown, and a round timer that keeps pace without interrupting your flow.

Round Timer: HIIT & Tabata helps you start, conduct, and monitor interval workouts on your iPhone.

Designed for those who want to drop their phone, glance once, and keep moving, this HIIT timer offers quick starts and clear guidance. The GO card launches your most recent workout instantly, so your go-to Tabata or interval timer is always just a tap away. During a session, the Live Activity and Lock Screen card show the current phase, remaining time, and controls, with pause, skip, or stop options right there. If you train with music, voice prompts speak over your audio before your music returns to normal, making it perfect for Tabata abs while watching TV, sprint repeats on the track, or boxing rounds at the gym.

• Launch your last workout instantly from the GO card on Quick Start. • Choose from presets like Classic Tabata, Beginner HIIT, EMOM 10, AMRAP 20, Boxing Rounds, and Sprint Intervals. • Create custom workouts with your own work, rest, rounds, warm-up, and cooldown times. • Select a protocol such as Tabata, HIIT, EMOM, AMRAP, Circuit, Rounds, Sprint, or Custom. • Add specific labels per round so voice prompts say Burpees or Push-ups instead of a generic work cue. • View a large full-screen countdown with colour changes for work, rest, prep, cooldown, and finish. • See the next step with the UP NEXT preview and a round counter. • Control sessions with big Restart, Play/Pause, and Skip buttons. • Optionally start a playlist from your music library automatically with saved workouts and stop it when done. • Keep prompts running with the screen locked, plus optional haptics on each phase change. • Review History for this week’s sessions, total time, streaks, and session details, then share or delete as needed. • Start workouts from Home Screen, Lock Screen, Control Centre, or shortcuts for quicker access.

It suits real training moments. Start Classic Tabata for a quick core set, build a Circuit for a class, run EMOM 10 in a garage gym, use Sprint Intervals for repeats, or watch Boxing Rounds from across the room. Pro lets you keep one clean record by saving each completed session as a single workout in Apple Health.

The free version lets you save up to 3 custom workouts. Pro lifts this limit and adds Apple Health saving for finished sessions. Music access is only needed if you want your playlists to start with workouts, and Health access is only necessary to save workouts.

Pick a preset, tap GO, and turn your iPhone into a clear, reliable HIIT timer for Tabata, EMOM, AMRAP, boxing rounds, and more.
