RhythmCount: Rep Counter

Stop hunting for the right workout preset. RhythmCount watches your very first rep and learns the shape of that movement — then counts every rep after it, for any exercise you can think of. Squats, curls, jumping jacks, burpees, lunges: if you can repeat it, RhythmCount can count it.

HOW IT WORKS
Stand where the camera can see the body part that moves, then do one clean rep to teach the app your motion. From that moment on, on-device pose AI tracks the pattern and counts automatically. A short countdown gives you time to get into position before each round, and an optional auto-start mode begins counting the instant you start moving — no tapping required mid-set.

WHAT YOU CAN COUNT
• Strength moves — squats, lunges, push-ups, curls, presses
• Cardio bursts — jumping jacks, high knees, mountain climbers
• Anything repetitive — physical therapy drills, sport-specific reps, or a movement nobody's ever named

Because RhythmCount has no fixed exercise library, it works for the workout you're actually doing today, not just the ones a developer thought to program in advance.

YOUR PRIVACY, GUARANTEED
RhythmCount's pose tracking runs entirely on your iPhone. Camera frames are processed on-device and never leave your phone — nothing is uploaded, stored, or shared with anyone, including us. You get AI-powered rep counting without ever sending your camera feed anywhere.

FAIR, SIMPLE PRICING
Every day you get 5 free rounds, no strings attached. Need more on a big training day? Watch a short rewarded ad for one extra round, as many times as you like. Or skip the ads for good with a small one-time purchase that removes the daily cap forever — pay once, count forever.

BUILT FOR REAL WORKOUTS
No sign-up wall, no account, no subscription creep. Open the app, show it one rep, and start counting. RhythmCount adapts to you — your form, your pace, your exercise — instead of asking you to adapt to it.

Download RhythmCount and let your first rep do the teaching.
