Form scoring, calibrated to your body
Your form isn't wrong. It's yours.
Textbook angles assume a textbook body. Formerly measures your femur, torso and ankle range first — then scores every rep against the numbers that are actually correct for you.
Four guided poses, ninety seconds, once. Phone only — no wearables.
Femur to torso ratio 1.14. Long legs relative to your back means a 52° torso angle is correct posture for you — flagging it at the textbook 45° would be coaching you into a worse squat.

What you actually get back
Not a vibe. A score, the two or three things to change, and the exact frame each one came from — so you can check the coaching yourself.
Back squat · 5 reps · 60 kg
18 Aug · Rep 4 flagged · Confidence high
Depth is there — hold the position
Hip crease passes below the knee on every rep. You're rushing out of the bottom about 0.3s early, which is where the lean creeps.
Frames 5, 6 · Rep 4
Left knee drifts in at the bottom
14° of inward travel on rep 4 — under the 15° safety limit, but it only shows on your last two reps. Push the floor apart as you stand.
Frame 6 · Safety threshold, not personalised
Torso angle is correct for you
52° measured against your 52° target. A generic checker would have marked this down.
Frames 4–7 · From your calibration, 6 days old
How it works
Measure yourself once
Four poses in your bedroom: T-pose front and side, a bodyweight squat, an overhead reach. We read your proportions and ankle range, then tell you what your numbers mean before saving anything.
Film one set
Phone propped against a water bottle, side on. Any exercise. Ten frames get read against your thresholds, not a generic model of a body that isn't yours.
Read the report, change one thing
Two or three cues, ranked, each pinned to the frame it came from. Safety limits stay fixed — knee travel and back rounding are never personalised away.
