RoundFlow is the round timer you can pay for once and keep forever, and it doesn't kill your music. It keeps timing with the screen locked, ducks your music for the bell, then hands the volume straight back. Start Spotify, Apple Music or YouTube Music, hit START, lock the phone and train. Your playlist never stops. A COACH IN YOUR CORNER • A real recorded coach voice calls your rounds, rests and the final "3-2-1" • Combo calls shout live combinations — "Jab, cross, hook!" • Bell, coach voice and haptics — or switch to a built-in system voice INTERVALS INSIDE THE ROUND • Split any round into hard and easy bursts — 10 seconds hard, 10 seconds pace, nine times, inside a 3-minute round • The bell still means the round. The switches are a short tick, high going in hard, low going easy — not 200 bells a session • The ring turns amber while you ease off, so you can read it from across the gym without counting • A longer break every fourth or eighth round, on top of the normal rest • One toggle and three numbers to set up, or start from a ready-made Burst Rounds, Sprint Rounds or Long Session HANDS-FREE WHEN THE GLOVES ARE ON • Hold a hand over the top of the phone for a second to pause, and again to carry on • Or say "Pause RoundFlow" to Siri — no glove comes off either way BUILT FOR EVERY ROUND • Boxing, Muay Thai, MMA, kickboxing, taekwondo, karate, CrossFit, HIIT, Tabata, sprints & running • Two custom profiles free, unlimited with Pro: rounds, round time, rest, warm-up, cool-down and warning • A big, glanceable timer ring you can read from across the gym RUN & SPRINT • Roadwork — a GPS run tracker built for fighters: distance, pace, kilometre splits and a goal for the session • Sprints — interval sprint sessions with the same bell, coach voice and rest countdown as your rounds • Every run lands in the same training log as your rounds MADE TO SHARE • Workout DNA — every session draws a one-of-a-kind piece of art from your training, ready for Instagram Stories • Your RoundFlow Year — a Wrapped-style recap of everything you've put in • Challenge a friend — send any workout as a link, then compare your scores TRAIN TOGETHER • Group sessions in perfect sync — everyone hears the bell at the same moment • Present mode — mirror the timer to a TV or projector for the whole class TRAIN WITHOUT LOOKING • Live Activity & Dynamic Island keep the round live on your Lock Screen • Apple Watch companion — a haptic on every bell, plus live heart rate, punch count and Effort Score.
