Disc-i
A disc-sports coaching app that analyzes backhand, forehand, and putting form from slow-motion video.
What to know
Disc-i covers ultimate as well as disc golf. A slow-motion clip is filmed from the side or from behind for backhand and forehand, or head-on for putting (listed for iOS), then uploaded. The app picks out key moments, measures joint angles against pro ranges, scores arm path, brace, coil, off-arm and posture, and suggests a quick fix. Its FAQ warns that the first analysis can fail to complete.
More detail
Side-by-side comparison with a named pro uses forms bought one at a time, such as Robert Burridge's at $19.99, with proceeds going to touring pros. It is free to try, and the Solo plan is $69.99 a year for unlimited analyses across iOS, Android and the web. Team plans run from 4 players at $188.99 to 100 at $1,889.99 a year. The App Store listing says prices will rise as features are added, and the app was updated in late August 2026.
