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. Your first analysis is free.

Verdict

The call

The clearest difference is ads: RepLens at none against Lyfta's shown. RepLens also leads on rating (5.0 vs 4.8) and review sentiment (100% vs 86%). Lyfta's advantage is ratings volume (6.9K vs 1) and chart position (#60 vs unranked). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Lyfta sells 10 in-app purchases, starting at $5.99 per month and RepLens sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
