On-device AI form analysis
Then get one cue, and retest. FormVision draws the line your barbell actually traveled and tells you the single thing to fix on your next set — your first analysis is free.
The big three
Each lift has its own analyzer, tuned to what a side-on camera can measure reliably — with explicit target ranges you can see.
Also in: Olympic lifts — snatch & clean tracked in bar-path mode, the trail colored by speed. Every new movement ships only after it's validated in a real gym.
How it works
Prop your phone at the side and record with your camera — full body in frame. Any lift you already filmed works too.
The exact line your barbell traveled, traced automatically off the plate — no markers, no tapping the screen. Plus bar speed in m/s, rep by rep.
Not a wall of data — the single thing to change, in gym language: "bar drifts forward — keep the weight over midfoot."
Film the next set and watch the line straighten. Run the same loop for four weeks with a plan built around your weakest metric.
Why trust the numbers
If the camera can't measure it, we don't show it.
Most form-check apps grade everything — and are wrong about half of it. You notice by week two, and you delete the app.
FormVision only shows numbers that are reliable from a side-on camera, against target ranges you can see. What can't be measured honestly is left out, on purpose. And it's form analysis, not medical advice.
YOUR VIDEOS NEVER LEAVE YOUR IPHONE.
