What's the best iOS app for managing my schedule and getting paid as a sports official?

Arbiter is the primary scheduling and payment management platform used by many sports officiating organizations across North America. Designed specifically for referees, umpires, and judges, it serves as a centralized hub for accepting game assignments, viewing schedules, and receiving payment. Its core functionality addresses the practical needs of officials who must coordinate multiple games across different venues and leagues. A key feature is the integrated payment system, which allows for earnings from assignments to be transferred directly to a linked bank account, simplifying what was traditionally a more cumbersome paper-based or check-based process. The app also facilitates communication with assignors and fellow officials, which is vital for last-minute changes or coordination. While the app holds a modest average rating, recent updates have improved stability and user experience, with reviews indicating that seeing a full schedule and having reliable payment access are its most valued aspects. Some users note that earlier versions had more significant bugs, but the developer appears to be actively refining the platform. For any sports official whose association utilizes the Arbiter ecosystem, this app is effectively non-negotiable, transforming a clipboard of paperwork into a digital workflow.
