About Whistle
Whistle is a HuddleUp Sports app where leagues and towns post games and sports officials — referees and umpires — claim them and get paid. Officials see the pay for each game up front, claim the ones they want, and get paid fast and securely through Stripe once the game is marked complete. Whistle is sport-agnostic, free for officials to join, and shares a single account with HuddleUp. Learn more on the Whistle product page or log in to Whistle.What is Whistle?
What is Whistle?
Whistle is a HuddleUp Sports app that connects sports officials with the leagues that hire them. It’s a two-sided platform: leagues and towns post their games, and officials — umpires and referees — browse open assignments, claim the ones they want, and get paid. Pay for each game is shown up front, so officials always know what they’ll earn before they claim.
Who is Whistle for?

HuddleUp is the app for families, coaches, and leagues — schedules, rosters, registration, and team communication. Whistle is the app for officials and the leagues that hire them — claiming games and getting paid. League organizers use both: they run the season in HuddleUp and fill and pay their officiating crew in Whistle.
