RefScore is the app for sports officials whose organizations use RefScore to assign games, evaluate officials and pay them. GAMES See every assignment with its date, venue, crew and pay. Accept or decline from the notification, and check in on game day. AVAILABILITY Mark the days you can work and send the month to your assignor. REFSCORE Your evaluation score, with category breakdowns and how it has changed over time. EVALUATIONS Read your completed evaluations and the comments behind the numbers. Observers can record voice notes at a game; with their consent the recording is transcribed into a draft evaluation. MESSAGES Message your assignor, the crew for a game, or RefScore support. Report a message or block a crewmate from inside the conversation. PAYMENTS Set up payouts once, then track what is pending and what has been paid. FIND GAMES Browse open games and tournaments from organizations looking for officials. An invitation from your assignor connects your account to your organization. Without one you can still set up your profile and availability and see how RefScore works.

Verdict

The call

The clearest difference is in-app purchases: RefScore at none against By Rule's 2. RefScore also leads on update cadence (every 5 days vs every 3 weeks) and iOS requirement (15.1 vs 18.0). By Rule's advantage is ratings volume (20 vs 2). On price, rating, ads and device support there is nothing between them.
