Film one set on your phone. RepCheck's AI reads every joint angle, scores your technique, and tells you exactly what's costing you gains, or setting up your next injury.
Launching on iPhone & Android · Founding waitlist open now
Sample footage, in the app you just film your set.
Most lifters train alone, and mirrors lie, you can't watch your own knees at the bottom of a heavy squat. RepCheck turns any phone into the coach's eye: frame-by-frame joint tracking on every rep, plain-English fixes, and progress you can actually measure.
Any angle, any gym lighting. No wearables, no sensors, no setup, the camera you already carry is the hardware.
Hips, knees, ankles, spine and bar path, measured on every rep, compared against sport-science standards for each lift.
Plain-English cues ranked by injury risk, plus a form score per lift so you can see technique improve week over week.
RepCheck launches this fall. Waitlist members get 50% off — locked forever.
No charge today. We'll email you on launch day with your founding discount, you decide then.
At launch: squat, deadlift, bench press, overhead press, barbell row, and hip thrust, the lifts where form matters most and injuries cost the most. More movements ship monthly, and waitlist members vote on what's next.
No. Prop your phone against a water bottle or use a cheap tripod. The AI is trained to handle typical gym lighting and imperfect angles, and it tells you if a clip is unusable before counting it against anything.
It's the layer most lifters never had: objective, every-session feedback. It doesn't diagnose injuries or replace medical advice, if something hurts, see a professional. It will, however, flag the movement patterns that commonly lead there.
First access at launch this fall, a founding discount of 50% off the public price for as long as you stay subscribed, and a founding badge in the app. Joining is free and there's no charge before launch.
