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. WHO IT'S FOR Whether you're new to the barbell or chasing a PR, RepLens gives you the second set of eyes most lifters never have - without a coach's price tag or a gym mirror full of guesswork.

Kinetriq — Movement Intelligence for Fitness Professionals Stop guessing about form. Kinetriq turns your device into a biomechanics lab — analyzing exercise technique and movement quality from live camera or saved video, entirely on-device. Kinetriq requires a Kinetriq Pro subscription. New users get a 7-day free trial.

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). Supported exercises include: • Squat, Deadlift, Lunge • Hip Hinge (side and back views) • Barbell Row • Lat Pulldown / Chin-Up (side and front views) • Overhead Press • Elbow / Bicep / Tricep curls Each exercise includes camera setup guidance so you get clean, trackable footage every time. 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. Live or saved video • Live Camera — real-time overlay, rep counting, and optional recording with analysis baked in • Saved Video — analyze client check-ins, form checks, or content you've already filmed Export and share Generate an analyzed video with skeleton overlay, angles, and metrics — ready to send to clients or drop into your next Reel, TikTok, or YouTube tutorial.
