Race yesterday's you
Swim analytics for one swimmer at a time
Long Whistle turns a young swimmer's own races into something they can actually read — splits, turns, where the race was won and where it slipped away. The comparison is always to their last race. The rival is never another kid.
Their own races
Splits, turns, and pacing taken from the races your swimmer already swam. No projections against a field, no percentile against a state list — just what happened, and what changed since last time.
Built for families
Made by a swim parent, for the people in the stands. It is not a club management system and it does not need one. A parent can use it from the deck without setting anything up with a team.
No leaderboards
There is no kid-versus-kid ranking anywhere in Long Whistle, and there never will be. Progress is measured against the swimmer's own history, not against anyone else's.
Your data stays yours
Race data is stored on your own device and belongs to the parent who entered it. We do not run trackers, we do not sell anything to anyone, and we do not need an account to let you use the app.
Where things stand
The Long Whistle app is in active development and is not on the App Store yet. This site is where the privacy policy, support contact, and eventually our writing on swim training research will live.
Questions, or want to hear when it ships? Email support@longwhistle.com. There is no mailing list and no signup form — a note to a human is the whole system.
