What's the best iOS app for running a multi-round golf tournament with live scoring?

Golf GameBook is a strong contender for managing golf tournaments of various sizes. Its core functionality extends beyond a simple personal scorecard to offer comprehensive tools for organizing and scoring group events over multiple days. Organizers can set up different formats, define teams, and establish handicaps. The app's live scoring feature is a significant draw; as players input their scores hole-by-hole, a shared digital leaderboard updates in real time. This allows participants not on the same course, and even spectators, to follow the action remotely. Specific features like GPS distance measurement for shot tracking and the ability to add detailed shot notes add depth to the post-round analysis. Users report that the interface is straightforward for both administrators and players, which is crucial for smooth event operation. However, some note that accessing the full suite of tournament management features requires the premium subscription. The app's reliability in maintaining live scoring data across large groups is frequently cited in reviews as a key strength.
