Plouf Check! Swim & Drink

Is the beach water good today? And the water from your tap? Plouf Check! answers both. Free, with no account, no advertising, no tracker. 1. BEACH WATER - 2,097 beaches on the French coast, those of the official health monitoring. - Two readings: the regional health agency's rating, and a score recalculated using the method of Eau & Rivières de Bretagne, stricter on one-off pollution. - Plouf Check score: a score out of 100 you grasp at a glance, with its calculation window shown. - Sharing: your beach's water quality as an image. 2. TAP WATER - All 34,969 French towns. - The unit is the distribution network, not the town: it is the network that feeds your tap, and two neighbourhoods of the same town can drink two different waters. The app names the network each verdict comes from. - What is measured: bacteria, nitrates, pesticides and their metabolites, PFAS (the 20 regulated ones and the 4 most concerning), vinyl chloride, perchlorate, free chlorine, limescale. - Two rates rather than a score: quality limits, and quality references. No invented score — these are the health monitoring's own. - What "compliant" does not say: substances found below their threshold are named, with their value and that threshold. - Five years of records per town, year by year. Downloaded once, readable afterwards with no network. - Search by name or postcode, and geolocation. 3. TIDES, EVERYWHERE ON THE COAST - The tide everywhere along the shore, not only in the major ports, thanks to Ifremer's high-resolution data. - 100% offline: the computation runs on your device, with our own engine. Even in airplane mode. - Tide coefficient (Channel-Atlantic coast), rate of water level change in m/h, water and air temperatures. ON ANDROID - Material 3 dynamic colour: surfaces follow your wallpaper. The sky and the water-quality scale never do. - No Google: the map is MapLibre on OpenFreeMap tiles, location comes from the Android service. No Play services required. - Tide alert thirty minutes before each high tide of your first beach, off by default. ON THE WRIST (WEAR OS) - Standalone watch app: tides computed without the phone, tap water included. - A "Tide" tile and a watch face complication: short text, progress ring, long text. WHAT THERE IS NOT - No account, no advertising, no in-app purchase, no advertising tracker, no data broker. - Your location never leaves your device: it sorts beaches by distance, then it is forgotten. - Anonymous usage statistics go to a server owned by the developer, hosted in France: which screens are opened, which settings change. Never the name of a beach or a town, never your position. Switched off in one gesture. - Free, and it stays free. Tide predictions cover the astronomical tide alone and do not include the weather. The app is not an official nautical document. Tap water analyses are past official records, published about two months late, and cover the distribution network: they do not describe the state of the water at your tap right now.
