Read full descriptionHide full description
TRACK EVERY LEAD-HAND PUNCH. TRAIN LIKE A PRO. Transform your Apple Watch into a professional boxing tracker. Jab Counter automatically counts punches, classifies strike types, and measures impact during heavy bag workouts, shadow boxing, and pad work. Just strap on your Watch and start hitting. The app handles the rest. ROUND TIMER Set custom rounds, duration, and rest time directly on your Apple Watch. A bell sounds at the start and end of each round. Punch detection pauses automatically during rest so your stats stay clean. See per-round breakdowns after every session. AI PUNCH CLASSIFICATION (Beta) An on-device AI model identifies jabs, hooks, and uppercuts in real time. See a color-coded breakdown on the watch summary and iPhone detail view. No cloud connection required. PRO-GRADE BOXING ANALYTICS • Punch Volume: Total lead-hand count plus per-type breakdown (jab, hook, uppercut). • Punch Dynamics: Peak, average, and per-punch acceleration (G-force) with relative power for every strike. • Round-by-Round Stats: Punch count and force distribution for each round. • Punch Rhythm: Frequency tracking to measure stamina and output over time. • Heart Rate Zones: Detailed breakdown of your cardiovascular effort. • Health Integration: Syncs automatically to Apple Health. TRAINING TRENDS Track your progress month over month on iPhone. See totals and averages for training time, punch volume, and calories burned. Trend lines show whether you are improving or declining. VISUALIZE YOUR PROGRESS Analyze every session with acceleration charts and punch frequency graphs. See exactly when your intensity peaked and where your rhythm dropped, color-coded from light to explosive. BUILT FOR THE GYM Whether you are hitting the heavy bag, working the pads with a coach, or shadow boxing at home, Jab Counter gives you the data to level up. A NOTE ON ACCURACY For best results, wear your Apple Watch on your lead hand (the hand you jab with). Jab Counter is optimized for lead-hand volume and intensity. High-energy activities like jump rope may register as light punches and can be excluded using the "Exclude Intervals" tool.

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.
