Gfrör.li allows you to view the water temperatures of different locations at Swiss lakes in real time. So you always know if the water is warm enough for swimming, water skiing or any other water related activity.

The data is collected and transmitted by self developed sensors every 15 minutes.

The app includes the following features:
- The map view gives you an overview over all locations and their temperature at a glance.
- In the detail view of a location you can find its current temperature, the maximum and minimum values, and a graph of its temperature history.
- Using the search function, you can easily search and filter the locations according to the current temperatures or other properties.
