Prop your phone, lift, and get an A–F grade on every rep — hands-free. On-device AI counts your reps and grades your form in real time. No video ever leaves your phone. Just lift. Your phone counts and grades every rep. CalmArms turns your phone into an AI form coach. Prop it up, start your set, and CalmArms watches every rep — counting it automatically and grading your form A to F in real time. No tapping, no counting, no touching the screen mid-set. When you train alone, it's the second set of eyes you never had. WHY CALMARMS • Grades every rep, not just counts it — joint angle, range of motion, tempo, stability, and left-right balance, scored A–F. • Hands-free — set your sets up front, punch in the weight after each one, and never count a rep. • On-device & private — pose detection runs locally on your phone. No video is recorded, stored, or uploaded. Ever. • Works anywhere — garage, basement, hotel gym. No internet needed to grade a set. SUPPORTED EXERCISES (18 exercises, 59 variations) Arms — bicep curl, tricep extension Shoulders — shoulder press, lateral raise Chest — bench press, pec deck, chest fly Back — lat pulldown, pull-up, row Legs — squat, leg extension, leg curl, calf raise, deadlift (RDL, conventional, sumo, trap-bar) Core — crunch, sit-up, hanging leg raise More added regularly. HOW IT WORKS 1. Pick your exercise and number of sets. 2. Prop your phone so it can see you. 3. Lift. CalmArms counts and grades each rep live. 4. Punch in your weight after each set. 5. Review your grades, range of motion, and progress over time. TRACK YOUR PROGRESS Workout history, personal bests, average grades, and streaks — in the app or on the web at calmarms.com/dashboard. Built for solo lifters. Privacy Policy: https://calmarms.com/privacy-policy Terms of Service: https://calmarms.com/terms
