The main product experience today is the web app. There is mobile work in progress, but the supported, user-facing flow is still browser-first.
An AI rep counter uses computer vision to track your body's key joints (a pose-estimation model maps points like hips, knees, shoulders, and elbows) and watches how those joints move through each repetition. When the movement completes a full range-of-motion cycle, it counts one clean rep. Spotter runs this model on your own device, so it can count reps from a phone or webcam without any wearable, clicker, or sensor.
