Rounds is an interval timer that doesn't hold features back. Everything is free — unlimited timers, compound timers, the coach voice, music, widgets, Apple Watch and Apple Health. A REAL COACH Liam calls every round, every interval and what's next — 400+ exercises, from burpees to the Pilates hundred — "Round 3 of 8! Work!", "Next up: squats!" — over your music, with the screen locked. BUILD ANY WORKOUT • HIIT, Tabata and circuit builders • Custom timers with repeating groups inside groups • Change every work or rest interval at once • Folders and search — drag timers to rearrange them, or drop one on a folder to file it • Starter workouts: Tabata, HIIT, the 7-Minute Workout, a Pilates mat class, EMOM, boxing rounds and focus sessions IN CONTROL MID-WORKOUT Jump straight to any interval from the list on the workout screen — handy when a class runs long or short. Pause, skip back or skip ahead any time. START WITHOUT OPENING THE APP • Home Screen and Lock Screen widgets start a timer in one tap • Siri and Shortcuts: "Start Tabata in Rounds", "Start a 5 minute countdown in Rounds" YOUR MUSIC Works with whatever you're playing — Spotify, Apple Music, podcasts. The music dips while the coach talks, can pause on every rest, and pauses with the workout. Or pick an Apple Music playlist for any timer. ACTIVITY AND STREAKS Every workout lands in your history: your day streak, this week's minutes and a month calendar in your timers' colours. Workouts from your Apple Watch count too. SHARE A TIMER Send any timer as a link or a QR code. Friends open it and add it to Rounds in one tap. WITH THE PHONE IN YOUR POCKET The timer keeps running, beeping and talking with the screen off.

Tap the next interval to skip ahead. APPLE HEALTH Finished workouts are saved to Health with the workout type you choose. ALSO A one-tap countdown for rest between sets, and a stopwatch with laps.
