Out of pure love for cold water
BrrChecker was born from the question every open-water swimmer asks each morning: “Is it too cold today?” Instead of searching ten websites, there's now one answer – honest, fast and without data harvesting.
Lakes, rivers and sea – in seconds. With temperature history, sport ratings, water quality and a widget right on your home screen.
From a morning dip in the lake to a session at the sea – BrrChecker has the answer.
Current water temperature plus history over 7, 14, 30 days or the whole season.
Traffic-light colors instantly show whether swimming, SUP, kayaking, surfing or kiting fits right now.
EU classification, E. coli, enterococci and water clarity – explained in plain language.
Your favorite spot with temperature, trend and sport suitability – without opening the app.
Filter by minimum temperature and find the warmest waters first.
Beaches, parking, restaurants and pools on the map – including Look Around.
BrrChecker combines water temperature, wind and waves into a clear recommendation per sport. No more guessing at the shore.
You only decide after 5 days. No risk.
From official monitoring stations – BAFU (CH), GKD Bayern, PegelOnline (DE), Rijkswaterstaat (NL), AGES (AT) and NOAA (US) – complemented by Open-Meteo models for lakes and sea. Water quality comes from the EEA. For spots with their own measurement we use it directly.
The first 5 days are completely free. After that €4.99 per year – just over 40 cents a month, no ads and all features. Cancel anytime in your App Store settings.
The focus is on lakes, rivers and bathing spots across the DACH region and the Netherlands, plus North America's Great Lakes and selected coastlines. Coverage keeps growing.
The widget shows the last loaded values and refreshes automatically in the background once you're back online.
