How to film

Film from the side, camera at hip height, whole body in frame.

FORMA Form Check is in beta — treat the cues as a helpful second eye, not medical or coaching advice. 3D pose tracking works from most camera angles, though a clear side view is still the most accurate for depth cues. Always train within a safe, pain-free range.

What is FORMA Form Check?

FORMA Form Check is a free tool that turns your phone camera into a form coach. Film a set of any of 47 exercises and it counts your reps and flags form issues in real time, with a live skeleton overlay. It runs entirely on your device, so your video never leaves your phone and you don't need an account.

What you get

  • 47 movements — squats, hinges, presses, lunges, push-ups and more.
  • Runs entirely on your device. Your video is never uploaded, and no account is required.
  • Counts reps and flags form issues rep by rep, with a live skeleton overlay.
  • Reads 3D joint angles, so it works from most camera angles, not just a perfect side-on shot.
  • Free in your browser or the FORMA app.

How to use it

  1. Pick the exercise you're training.
  2. Prop your phone so your whole body is in frame, and allow camera access.
  3. Do your set — it counts reps and flags form issues live.
  4. Review the rep-by-rep feedback and fix it next set.

Frequently asked questions

Does AI form check actually work?

It's a genuinely useful second set of eyes, not a replacement for a coach. It uses on-device pose tracking to estimate your joint angles and flag common issues rep by rep — squat depth, a rounding back, an incomplete lockout. It won't catch everything a good in-person coach would, and it's still in beta and improving, so treat it as a helpful check rather than the final word.

Is my video private, or is it uploaded somewhere?

It stays completely private. The analysis runs locally in your browser on your own device, your camera feed is never uploaded to a server, and you don't need an account to use it. Nothing about your session leaves your phone.

Which exercises does it support?

32 common movements right now, including the squat, deadlift, bench press, overhead press, lunge and push-up. Pick your exercise, prop your phone so your whole body is in frame, and start your set.

Do I need to pay or make an account?

No. Form Check is free, there's no paywall on the tool, and you don't need an account to try it. Just open the page and allow camera access.

Form Check gives general movement feedback to help you train, not medical or professional coaching advice. If something hurts or you're returning from injury, stop and check with a qualified coach or healthcare professional.
