UDisc () is a disc golf app for scorekeeping, statistics, and discovery for smartphones and tablet computers running the Android or iOS operating system. The app is also compatible with Android's Wear OS and Apple Watch.

It gives access to an extensive community-driven course directory with user-submitted course condition updates, hole-by-hole navigation information about course layouts, and a chronological list of local PDGA-sanctioned events. Users can track the rounds they played, measure throws, track various performance metrics, and compete in worldwide leaderboards.

UDisc describes its app as the official app of the Professional Disc Golf Association. The app can be downloaded and used for free, but an optional in-app paid subscription to UDisc Pro unlocks more features.
