PickleWatch turns your Apple Watch into a real-time pickleball coach. 

Tap start and play, and it tracks every swing, recognizing serves, drives, volleys, dinks, and smashes, then grades your form with simple color-coded feedback: green for dialed-in, yellow for good, red for work to do. 

After each session, dig into swing speed, quality scores, and 7-day, 30-day, and all-time trends. No extra gear, no phone required. Free to download, with Pro for advanced analytics.
