RhythmCount
Read full descriptionHide full description
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.

YOUR SOUND, LOOPED Record ambient audio or import files and eligible songs from your music library. Trim and sequence loops, repeat sections, adjust timing, and render a saved mix to an audio file.

NEW: STUDIO Create beats and melodies, layer your voice, shape sounds, and save the result to your Loop Library. Studio includes pattern controls, voice layers, spatial and timing adjustments, and the Professor Fugue guide. You can also start or join a FaceTime SharePlay jam: participants share Studio settings and recorded voice layers through Apple's services. GENESIS Forge a soundscape, keep it, refine it or pass. Genesis learns from those choices on your device. Its taste memory is not sent to a learning server. Try 25 free forges; an optional one-time purchase unlocks unlimited Genesis forges. No subscription is required. MASKING AND COMFORT Use a tone or hiss band to estimate a sound resembling your tinnitus, then compare full and notched soundscapes. Prism Noise is a sound generator for masking and comfort, not a medical device or treatment. Results vary. Use a comfortable volume and seek professional care for new or changing tinnitus. YOUR DATA No developer account, advertising or tracking. Core sound creation works offline. Your files may sync through your own iCloud account. SharePlay requires a network connection and shares session content with people who join. Microphone and music-library access are requested when you use the related features. Support diagnostics are shared only when you choose. Privacy: https://www.prismnoise.com/privacy.html Terms: https://www.prismnoise.com/terms.html
