Plouf Check! Tides and Swim

Is the water clean today? 2,097 beaches, the official bathing score and the tide to the minute — worked out on your iPhone, even with no signal.

Plouf Check! is the essential app for your beach trips, combining the two most important coastal insights: tide times and water quality. Whether you are a surfer, a shore angler, or a parent wanting a safe swim, get clear scientific data, completely offline and with zero personal data collection.

ULTRA-PRECISE TIDES EVERYWHERE

• Local precision: Unlike classic apps limited to major ports, Plouf Check! gives you the tide at any point on the coast thanks to high-resolution data from Ifremer.
• 100% Offline: Calculations are performed directly on your phone via our custom engine. No network connection is required.
• Advanced indicators: Check the tidal coefficient (Channel/Atlantic coast) and the water level variation speed in m/h.

WATER QUALITY AND SWIMMING

• Double health assessment: Do not rely on a single indicator anymore. The app displays the official European rating (ARS) AND the strict ranking from the Eau et Rivieres de Bretagne (ERB) association for full transparency on pollution.
• Your favorite beaches: The interface focuses on your actual swimming spots (supervised beaches), not distant tide gauges.

DESIGNED FOR THE OUTDOORS

• Bright sun theme: Read your charts perfectly even in full sunlight on the foreshore thanks to our high luminance mode.
• Multilingual: Available in 7 languages (French, English, Spanish, German, Italian, Chinese, Russian).

100% ETHICAL

• Zero data collection: Your geolocation never leaves your device.
• 100% Free: No ads, no in-app purchases, no registration.
