## What is CalmArms?

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.

### 5/5 — Excellent Form Tutorial Videos

*2026-05-06*

As someone who is new to the gym, the form tutorial videos are super helpful and straightforward with none of the added bs that a Youtube tutorial videos would show.

### 5/5 — Great app!

*2026-05-06*

CalmArms is a great app and very easy to use! As someone who’s always been active but never had access to a personal trainer, I never realized how much my form was holding me back. This tool closes the gap between working out and working out correctly. Highly recommend.

We made getting to your set way faster — and gave the app a big cleanup.

• One-tap start: the camera now arms itself, lines you up, and counts you in with a 3-2-1. No more hunting for a Start button.
• Fewer taps to your first graded rep: Home has one clear button, and you pick your variation right on the exercise list.
• Redesigned camera setup: a bigger side-by-side demo clip so you can match the reference before you lift — now laid out correctly for landscape (sideways) exercises too.
• Progress tab glow-up: a cleaner dashboard with a real form-trend line so you can watch yourself improve.
• "Your form this month" now tracks correctly.
• New program — Anterior / Posterior: a 4-day front-vs-back split.
• Plus onboarding polish and stability fixes.

Keep lifting.
