Every match. Every decision. Your overview. FLUIT supports you as a referee from preparation to the final whistle. Manage your football or futsal match on Apple Watch and review it on your iPhone. YOUR MATCH ON YOUR WRIST Keep track of match time, score, half-time and extra time. Record goals, yellow and red cards, time penalties and substitutions. Select players by name and shirt number from your player list. You can also record the players going off and coming on during half-time. Your match log and haptic cues are close at hand. PREPARE ON YOUR IPHONE Plan your match and add teams and players. Scan a lineup or read both teams from a single match sheet. Check the recognised names, shirt numbers, starters and substitutes before importing and sending them to your paired Apple Watch. STATISTICS FOR YOUR MATCHES Explore your season, match events, distance covered and available heart-rate data. Choose two matches yourself to compare heatmaps, routes and measurements. View a whole match or a played period. Set your maximum heart rate to see measured effort in five colour-coded zones. Measurement coverage and missing data stay visible: not measured is not the same as zero. GPS and heart rate support your review; they do not rate your decisions or provide a medical assessment. YOUR PERSONAL RECAP From five available completed matches, view a milestone video featuring your match statistics and music. The video is created on your iPhone. You choose whether and where to share it, and which names appear; team names are hidden by default. FUTSAL Use settings for playing time, time penalties and numerical reductions. Time-outs and accumulated fouls are available where the selected variant supports them. Presets follow a Dutch rules context. Always check your competition's regulations. PRACTISE AND LEARN TOGETHER Test your knowledge in the Academy, read explanations and track your progress. Join challenges or organise a Laws of the Game quiz night with your referees' association. In your private Clubhouse, share selected summaries and discuss situations with other referees. Turn practice reminders on or off and choose their frequency. YOUR DATA, YOUR CHOICE Match measurements stay on your own devices by default. Only what you deliberately share goes to others. Location and Apple Health (HealthKit) are used with your permission. The scanner processes images locally. No advertising; optional usage analytics remain off until you consent. WHAT YOU NEED An iPhone with iOS 17 or later. The wrist-based match centre uses a paired Apple Watch with watchOS 10 or later. Planning, the Academy and existing reports are also available without a Watch. Online group features and map content require an internet connection. Measurements depend on your device, permissions and signal quality. Pitch orientation is an estimate; GPS is not an exact assessment of your positioning. The app is available in Dutch and English. Free, with no in-app purchases.
