How FORMA handles it
Prop your phone against a water bottle, hit record, and do your set. Form Check watches through your camera and draws a skeleton over your body so you can see what your joints are actually doing. It counts each rep and calls out issues as they happen, so you get feedback during the set instead of finding out after. It covers 32 exercises, the kind of compound lifts and accessory work most people actually train.
The part that matters most: everything runs on your own device. Your video never leaves your phone and isn't uploaded anywhere, and you don't need an account to use it. It's free, like the rest of FORMA's tools. When a flag tells you something's off, every movement links to a form guide with a demo so you can see the standard, and you can fold the lift into a plan built by Lock In or one of the 16 ready-made programs.
Where it's not the best fit
Be clear on what it is: a beta assistive tool, not a human coach or a physio. The rep counting and form flags are a decent second set of eyes, but the thresholds are first-pass, so it can miss things or flag a rep that was fine. Treat it as guidance, not a verdict. It only knows 32 exercises, so anything off that list won't be tracked, and it needs enough light and your whole body in the frame to read you properly. For a nagging pain or a real technique overhaul, see a coach in person.
Frequently asked questions
Is FORMA's form checker actually free?
Yes. Form Check has no paywall and needs no account. FORMA offers an optional Premium at about $12 a month, but that only removes ads and helps fund the project. It doesn't unlock Form Check or any other feature, so the form checker is the same whether you pay or not.
Does my workout video get uploaded anywhere?
No. Form Check runs entirely on your device using your camera. The video is processed on your phone or laptop and never leaves it, so there's nothing to upload and no footage sitting on a server. That's also why it works without an account.
How accurate is it?
It's a beta tool, so think of it as a second set of eyes rather than a certified coach. It's good at catching obvious things like a shallow rep or an uneven side, but the thresholds are first-pass and it can be wrong. Use it next to a form guide, and see a real coach for anything painful.
Which exercises does it cover?
32 of the common gym movements. Each one links to a form guide with a demo if you want to check the standard before you film yourself. Anything outside those 32 won't be counted, so it's built for the staples rather than every variation.
