About this app
CalmArms is a hands-free AI form grading app and rep counter for weightlifting. Prop your phone, start your set, and CalmArms grades your form on every rep and counts your reps automatically — no tapping, no manual logging, no touching the screen mid-set.
FORM GRADING ON EVERY REP
CalmArms uses on-device AI to watch your form while you lift, grading each rep from A to F in real time on five things a coach would check: joint angle, range of motion, tempo, stability, and left-right balance. It's real form grading, not just a rep counter.
AUTOMATIC REP COUNTING
Your reps are counted automatically as you lift. Set your number of sets up front, add the weight after each set, and CalmArms handles the rep counting and the form grading for you. You never count a rep.
THE COACH YOU TRAIN WITHOUT
When you train alone, nobody counts your reps and nobody checks your form. CalmArms is the second set of eyes — the training partner for people who don't have one.
ON-DEVICE & PRIVATE
All pose detection runs locally on your device. No video is recorded, stored, or uploaded — your camera feed is analyzed frame by frame in real time and immediately discarded.
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 exercises added regularly.
TRACK YOUR PROGRESS
CalmArms is also a workout tracker: view your workout history, personal bests, average form grades, and streaks — in the app or on the web at calmarms.com/dashboard.
