Jab Counter: Boxing Tracker

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

• Round-by-Round Stats: Punch count and force distribution for each round.
• Punch Rhythm: Frequency tracking to measure stamina and output over time.

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.
