Bad lifting form doesn't just stall your progress - it's what wrecks your joints. RepLens is your pocket form coach: record or photograph a set, and in seconds you get clear, specific feedback on what to fix and why. HOW IT WORKS 1. Pick your lift (squat, bench, deadlift, overhead press, row, pull-ups, dips, push-ups) 2. Add a photo or a short video from the side 3. RepLens tracks your body, finds your key rep, and grades your form 4. Get ranked, plain-English fixes - plus an AI-generated "ideal form" photo so you can SEE the correction on your own body BUILT TO CATCH WHAT MATTERS - On-device body tracking finds your deepest, most telling rep - Coaching judged against proven strength-training principles, not vague tips - Prioritized corrections, most important first - no jargon - A side-by-side "your rep vs. ideal form" so the fix actually clicks TRAIN AROUND YOUR PAIN Tell RepLens where you hurt - knees, lower back, shoulders - and it pays extra attention there, flagging the corrections most likely tied to your pain. Turn it off when the ache is gone.

Exercise form analysis Point your camera or pick a video from your library. Kinetriq overlays a live skeleton, tracks joint angles, counts reps, and breaks down tempo across four phases (eccentric, pause, concentric, pause).

Movement assessments Run structured screens with letter grades (A–F) and sub-metric breakdowns: • Shoulder Flexion (front and side views) • Squat Assessment — depth, torso lean, and symmetry • Hip Hinge Assessment — depth and spinal neutrality Assessments flag left/right asymmetry and use a weakest-link grading model — the same logic clinicians and coaches use when one limitation drives the overall result.
