Problem
Traditional golf swing analysis relies on video recording, tripods, and time-consuming setup, which disrupts practice flow and makes it difficult for golfers to get objective feedback during a normal range session. Many golfers lack access to professional coaching and need a simple way to measure swing quality without extra equipment.
Solution
PocketCaddie turns an iPhone into a swing coach by using the device's accelerometer and gyroscope to capture motion data while the phone rides in the golfer's front pocket. The app automatically detects each swing, eliminating the need for manual taps between shots, and scores the session with metrics like Swing Score, tempo grade, power tier, and hand speed. Apple Watch and AirPods can add wrist motion and audio feedback, while Android users can pair Wear OS or Garmin watches. After each session, the app generates a "Wrapped" recap with one actionable insight to work on during the next bucket of balls.
Target Audience
Amateur and recreational golfers who want objective swing feedback during practice sessions without the hassle of video equipment, as well as golfers who prefer a phone-based coaching tool that works at the driving range.
