A developer showed off PickleWatch, an app he built that logs swing speed, shot type, and hit quality from an Apple Watch worn on the swinging hand, then uses Claude Opus 5.5 to render the whole match as a 4-second replay map—each line a swing, ending on your fastest one. He notes the watch can't see the ball, so landing spots are best guesses inferred from shot type and speed.
