Whistle – Sports Officiating
Claim games. Get paid.
Free · Designed for iPad. Not verified for macOS.
Whistle is where sports officials claim games and get paid — and where leagues fill their crews.
FOR OFFICIALS
• Browse open games across the leagues you've joined and claim the ones that fit your schedule.
• See the pay up front, game by game.
• Track what you've worked and what you're owed, all in one place.
• Get a notification the moment a game you can claim is posted.
FOR ORGANIZERS
• Post your league's schedule and let approved officials claim slots.
• Approve the refs who request to join your league.
• Mark games complete and settle up — record payments made directly to your officials.
Whistle keeps youth and rec sports running: organizers spend less time chasing down officials, and officials spend less time chasing games and checks.
