UmpCrew

UmpCrew is umpire scheduling that finally works the way crew leads actually run things. Built for competitive, church, city, school, and rec leagues — softball, baseball, you name it. Stop running your roster out of a spreadsheet and a group text. WHAT YOU GET • Game-by-game assignments. Tap an open spot, pick an umpire, done. UmpCrew checks blackouts and concurrent games so you never assign someone who can't be there. • Smart availability. Umps mark their blackout days from their phone. You see who's actually free before you assign. • Text + push notifications. Every assignment goes out as a clean SMS with the game details and a one-tap calendar link. Push notifications too, for umps who want both. • Self-claim mode. Let your umpires grab open games themselves. You stay in control — admin review on every drop request before it's final. • Calendar handoff. Umps add games to Apple Calendar or Google Calendar with one tap. No copy-paste. • Game reminders. Automated text + push the night before. Fewer no-shows. • Pause-and-batch mode. Need to shuffle a whole week? Park the texts, review your changes, send them all at once. WHO IT'S FOR UmpCrew is for the person who runs the umpire crew — the church softball commissioner, the city rec league coordinator, the high school AD. If you've ever spent Sunday afternoons texting eight umpires to cover three games, this app is for you. Umps install the app to see their schedule, mark blackouts, and get reminders. Free for them. The crew lead pays a flat monthly fee per league. QUIET, FOCUSED, FAST No ads. No social feed. No leaderboard. Just the schedule, the crew, and the next game on the field.
