How it works
Fix your form in three steps
Record, analyze, improve — the whole loop lives on your phone.
Record
Film a squat, bench, deadlift, overhead press, or run — straight from your phone.
Analyze
AI pose detection scores your form and measures joint angles, depth & left/right asymmetry, then writes plain-language coaching.
Improve
Get a corrective plan for your weak points, log your workouts, and watch your form score climb over time.
AI that watches you move
Most apps log what you did. FormLens sees how you moved.
Exact joint angles, squat depth and left/right asymmetry — drawn right on your video, on every rep. Objective analysis you can actually see. No black box.
Features
Everything you need to train smarter
Form analysis, smart logging and personalized plans — all in one app.
Per-rep form score
Every rep scored 0–100, plus an overall for the set — so you see exactly which reps broke down.
Angles, depth & asymmetry
Exact joint angles, squat depth and left/right balance — measured on every rep.
AI video form analysis
Squat, bench, deadlift, overhead press and running — analyzed from a normal phone video.
AI coaching
Your weaknesses, primary issue, and the corrective exercises that fix them.
Corrective plans
A plan built from your measured weak points — not a generic template.
AI plan generation
Personalized, multi-week programs generated for you, plus ready-made templates.
Workout logging & PRs
Fast, Hevy-style logging with full history and automatic personal records.
Exercise library
A full library of movements — add your own custom exercises too.
Progress charts
Form-score trend, training volume and muscle-group distribution over time.
Streaks & consistency
Streaks and consistency tracking that keep you coming back.
Why FormLens
The only app that does all three
Logging apps track what you did. Form-check apps grade a single lift. FormLens does both — then builds your plan.

Why FormLens
We built it to show how you moved — not just what you lifted.
Most trackers count your reps and weight. None tell you whether those reps were any good — so bad habits compound, progress stalls, and small tweaks turn into injuries.
FormLens reads your actual movement from a normal phone video, on your device, and turns it into a score, exact numbers, and a plan. No wearable, no $80-a-session coach — just the camera you already own.
Quality, not just numbers
Every rep scored on how you moved.
Private, on device
Your videos are analyzed on your phone.
No coach, no wearable
Just the camera in your pocket.
