Frequently asked questions
What's the difference between HuddleUp and Whistle?
HuddleUp is the youth sports app for families, coaches, and leagues — schedules, rosters, registration, and team communication in one place. Whistle is the app for sports officials and the leagues that hire them — referees and umpires claim open games and get paid via secure Stripe payouts. Both are part of HuddleUp Sports.
How do HuddleUp and Whistle work together?
League organizers are the bridge. A league runs its teams, schedules, and registration in HuddleUp, then uses Whistle to post the same games for officials to claim and to pay those officials automatically. One organization, one account, both tools.
Do I need a separate account for each product?
No. Whistle and HuddleUp share a single HuddleUp Sports account. Your role lives on each league membership, so the same login works whether you're a parent, a coach, a league organizer, or an official.
Who is each product for?
HuddleUp is for parents and families managing kids' sports, coaches running teams, and leagues administering seasons. Whistle is for officials who want paid games and for leagues and towns that need to fill and pay their officiating crew.
Is it free?
HuddleUp is free for families and affordable for leagues with no per-team charges. Whistle is free for officials to join and claim games. Leagues use it to post games and pay officials through secure Stripe payouts.
