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!

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 gfrör.li.

WhatsNew:

- Add a "locate me" button to the map, which shows your position and centers
the map on it.
- Remember the map position and restore it when reopening the app.
- Add experimental Android Auto support: Browse nearby water temperatures and
navigate to a sensor location. (Google Play only)

Anti-Features:

TetheredNet (This app is bound to a certain network service):
⇒ The app is bound to a server using the libre Gfrörli API, but you cannot change the server.

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device. Some clients have this repo enabled by default, e.g. Neo Store, Droid-ify, or, of course, the IzzyOnDroid client by Sunil. With others (like the official client) you'll have to add this repo manually (see the hint on top of the package list for how to do that).
