Partial The app UI and stats tracking are vibe-codeable, but automatically identifying shot type, in/out calls, and swing quality from a phone video needs trained computer vision models that a solo builder cannot easily produce.
What it would actually take: The stack would combine on-device pose estimation (for example MediaPipe or a similar model) with ball detection and tracking, then a court-calibration step to map landing spots. Accuracy requires labeled tennis footage, which must be collected and annotated. Expertise in computer vision and sports biomechanics, and time to tune models across phone cameras, is the main requirement.
