RipReader

Measure disc golf throw speed, accuracy & distance with just your phone.

Measure your disc golf throws with your phone.

RipReader turns your phone's high-speed camera into a throw analyzer. Set your phone on the ground, throw your disc, and get instant metrics. No extra hardware required.

RipReader measures velocity so you know your actual arm speed and GPS distance from your throw to the landing spot. 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 compare 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.

Capture an entire field session, then review everything after.
