About RepLens

RepLens is an AI fitness app that helps lifters understand what their reps actually look like. Upload a training video and get clear, practical feedback on form mistakes, injury risk signals, range of motion, tempo, and movement quality.

We built RepLens for people training without an in-person coach, and for trainers who want a better way to review client footage remotely. The goal is simple: make better feedback more accessible than a mirror, and more affordable than constant one-on-one coaching.
