<p>The app "Gfrör.li" displays current water temperatures of Swiss lakes and rivers in dozends of different locations. Ideal for temperature-sensitive people that still like swimming outside when the temperature is sufficiently high!</p><p>The data displayed comes from our community-operated LoRaWAN based measuring stations and is updated multiple times per hour. Additionally, we integrate data from public measuring stations (like from the Swiss FOEN) when the license permits us to do so. You can find more information about the project at <a href="https://gfrör.li/" target="_blank" rel="noindex nofollow noopener">gfrör.li</a>.</p><p></p>
