Today we’re launching Whistle — a new app from HuddleUp Sports built for the people who make games possible: the officials. If you’re a referee or umpire, Whistle is the fastest way to find open games near you, claim the ones you want, and get paid for every call. And if you run a league or a town rec program, it’s the simplest way to fill your crew and pay them without the spreadsheet headache. Log in to Whistle →

The Problem We Set Out to Fix

Officiating runs on a system that hasn’t changed in decades. Assignors juggle phone trees and group texts. Officials find out about open games through a chain of forwarded emails. And once the game is over, getting paid means waiting weeks for a check in the mail — or chasing down a league treasurer who’s “getting to it.” Every part of that is friction. Good officials walk away from the game because it’s too much hassle for too little reward. Leagues scramble to cover games because they can’t fill their crews fast enough. Everyone loses. Whistle replaces all of it with one app.

What Whistle Does for Officials

If you officiate, Whistle is built around three steps:
  1. Find open games — Browse leagues near you and see every open assignment, with the sport, date, location, and pay shown up front. No more guessing what a game is worth.
  2. Claim your games — Tap to claim an open slot. Claiming is race-safe, so a game is yours the moment you grab it — no double-booking, no phone tag with assignors. Your calendar updates instantly.
  3. Get paid — Officiate the game, and once the organizer marks it complete, you get paid fast and securely through Stripe — straight from the field to your wallet.
That’s it. No invoices, no waiting on checks, no wondering when the money is coming. Start claiming games →

What Whistle Does for Leagues and Towns

Whistle is a two-sided platform, which means it also solves the other half of the problem — the people posting the games.
  • Post your whole season in seconds. Create your league and bulk-add games, then set the pay for each crew slot.
  • Fill your crew. Approve the officials who request to join and watch open slots get claimed by qualified, rated refs.
  • Pay everyone automatically. Mark a game complete and Whistle handles the payouts — secure Stripe transfers to every official, with no manual bookkeeping.
You stop spending Sunday nights texting refs and start running a season that fills itself.

Every Sport, One App

Whistle is completely sport-agnostic. Baseball, soccer, basketball, hockey, volleyball — if it needs a whistle, Whistle covers it. Officials build a single profile, collect ratings, and carry their reputation across every league they work.

How Whistle Fits with HuddleUp

Whistle isn’t a standalone product — it’s part of the HuddleUp Sports family, and it shares a single account with HuddleUp, our app for families, coaches, and leagues. Here’s how the pieces connect:
  • Officials use Whistle to claim games and get paid.
  • League organizers use both — they run their teams, schedules, and registration in HuddleUp, and post games, fill crews, and pay officials in Whistle.
  • Coaches and parents use HuddleUp to keep the season organized.
League organizers are the bridge. One organization, one login, both tools working together. You can see exactly how the two products fit together here.

What This Unlocks

When officiating is this easy, more good officials stay in the game. Leagues fill their crews faster and cancel fewer games. Towns spend less on administration and more on the kids. And the whole youth sports ecosystem — families, coaches, organizers, and officials — runs on one connected platform instead of a dozen disconnected ones. That’s the future we’re building toward, and Whistle is a big step.

Get Started Today
