A round and interval timer built for the mat. "6 rounds of 5:00, 1:00 rest" takes two taps, the countdown is readable from three metres away, and the timer keeps running when you lock the phone and drop it in your bag. ONE TAP TO START • Ready on first launch: Sparring 6 × 5:00, Drilling 8 × 3:00, Circuit 3 × 5 × 0:40. • Tap ▶ on any timer for a 3-2-1 countdown. Your last-used timer waits at the top. READ IT FROM ACROSS THE MAT • Huge digits, with nothing competing for the screen. • The whole screen floods with the colour of the phase: lime for work, blue for rest, violet for the long rest between circuits. You can tell the phase without reading anything. • The next interval is always shown, so you know what's coming. ROUNDS, RESTS AND CIRCUITS • Rounds from 0:05 to 60:00, rests up to 30:00, up to 20 circuits of 50 rounds. • Every round is the same by default. Switch to Custom to change any single round or rest: a longer last round, a shorter rest, an extra round at the end. • The total session time is shown before you start. A SOUND FOR EVERY CUE • 38 original sounds in six sets: classic gym, loud & long, coach voice, calm, dynamic and fun. • Pick a sound and volume for each moment: round start, rest, long rest, halfway, last 10 seconds, the 3-2-1 countdown and workout done. • Halfway and Last 10 seconds can be switched on for each timer. • Long, loud defaults you hear in the middle of a roll: the bell means go, the train horn means rest, the ship horn means long rest, the horn means done. • A 3-2-1 before the end of every round and rest. • Music from another app pauses for each cue and carries on right after (with the iPhone locked, it dips instead). • Optional voice callouts ("Round 3", "Rest", "Ten seconds") and haptics. KEEPS RUNNING ON THE LOCK SCREEN • Lock the phone or switch apps. The session keeps time and keeps playing its cues. • Live Activity on the Lock Screen and in the Dynamic Island, with Pause, Resume and Skip. • Pause, skip a round, or keep going exactly where you left off. ON YOUR WRIST • Roll Timer for Apple Watch shows the running timer full screen in the colour of the phase, with Pause, Skip and End. • Start any of your timers from the watch. The iPhone plays the cues out loud, so the whole mat hears them. • A tap on the wrist at every round, every rest and the end of the workout while the app is open on the watch. • With iOS 18 and watchOS 11, the Live Activity also appears in the Smart Stack on your Apple Watch. MADE FOR THE GYM • The screen stays on and bright during a session, at the brightness you choose. • Works offline. No account, no ads, no tracking. • In 9 languages: English, Português, Español, Français, Deutsch, Italiano, Polski, Русский and 日本語. For Brazilian jiu-jitsu, grappling, wrestling, judo, sambo, MMA, boxing, kickboxing, Muay Thai, HIIT, Tabata, circuit training and open mat. ## Is Roll Timer safe?
