What only Whistle ships.

Features the legacy tools haven't caught up to.

Whistle exclusive

One-click Auto-Assign Engine

A scoring engine that weighs availability, rating, distance, and fatigue — fill a full weekend of games before competitors have finished importing their schedule.

Game Up For Grabs

An official can't make it? The game posts to a live marketplace and a vetted ref claims it — no scrambling phone calls.

Anti-Cherry-Picking

Declining a league assignment hard-blocks that time slot. Refs commit; leagues stay protected from the high-pay swap game.

Native mobile + web. One platform.

Organizers stay on the dashboard. Officials live in the app. Hosts post from either. Same login, same data, same UI language — not a duct-taped companion app.

Games, Leagues & Tournaments

Post a single weekend game or run a bracketed tournament — all from one dashboard, no separate products to license.

Coming soon

Payments + Payroll Tracking

Track every game fee. Reconcile payroll in one view. In-app Stripe payouts arriving soon — no checks, no third-party portal.

Real-Time Notifications

Push and in-app notifications for new games, releases, accepts, and roster changes — not buried email digests.

GPS Check-ins

Officials check in from the field through the app. Location is used only during active check-in — privacy-first by design.

Switching is the easy part.

Bring your roster, your pay rates, and your existing schedule. Whistle's onboarding gets a full league live in a single sitting — no consulting calls, no quarterly licensing call.
