Sendyy

Set your phone on a tripod, film a stronger climber sending the problem, then film your own attempt from the same position. The app aligns the two clips, detects each climber's hand and foot contacts, derives the route from the reference climb, and splits both climbs into moves. Moves are grouped into sequences bounded by the holds both climbers actually used, so you compare like for like even when your beta takes three moves where theirs took one. For each sequence you get side-by-side and overlay playback plus a breakdown of what differed, hip distance from the wall, limb loading, joint angles, timing and hesitation, all normalized by body length, so a height or weight difference never shows up as a mistake. If you fell, it traces the fall back past the moment you came off to the earlier sequence where the problem started. Everything runs on-device: no account, no upload, no network. Your climbing footage never leaves your phone.
