Measure your disc golf throws with your phone. RipReader turns your phone's high-speed camera into a $300 radar gun. Set your phone on the ground, throw your disc, and get instant metrics. No extra hardware required. Tap Start and place your phone on the ground or on a spare disc. Throw your disc and motion detection captures it automatically. Review slow-motion footage with your metrics overlaid. No button timing. No second person needed. Just throw. RipReader measures velocity and spin for every throw, plus GPS distance from your throw to the landing spot. Forehand and backhand are detected automatically. Every throw is saved with slow-motion playback, organized into sessions by date and location. An analytics dashboard tracks your averages, trends, and personal records over time. You can also build your disc bag, and after each session RipReader automatically matches throws to the right disc using on-device visual recognition and compares performance across different discs. Dedicated throw measurement hardware can run $300 to $400. RipReader works with every disc you own, runs on the phone already in your pocket, and costs a fraction of the price. RipReader is designed for players who practice with purpose. Auto-detection means you stay in your rhythm, no fumbling with buttons between throws. Capture an entire field session, then review everything after.
