An honest number from 1 to 10 per activity – swimming, SUP, kayak, surfing, windsurfing, kiting, pump foiling.Swimming free · all other activities with Pro
Every swim, dip and SUP session with the official water temperature – your Apple Watch leads the workout, the iPhone stays on shore.
Knots, gusts, onshore or offshore – and the best window of the next 48 hours at coastal spots.
EU classification, E. coli, enterococci and water clarity – explained in plain language.
Your favorite water on the home screen and Apple Watch – without opening the app.
Tell me when the lake tops 20° – the app pings you by itself.
Beaches, parking, restaurants and pools on the map – including Look Around.
Water temperature, weather, wind and waves, distilled into one honest number from 1 to 10. No more guessing whether the trip to the lake is worth it.
Because swimming isn't everything, the BrrScore rates each sport on its own – calm water for swimming, SUP and kayak; wind and waves flip the score for surfing, windsurfing and kiting. A tap shows you exactly how the number is made: water, air, surface, sun. No black-box algorithm.
