The most important functions: seamless zooming, change of scale, positioning (GPS) including Moving Map, and recording of waypoints and routes.
Swiss Map Mobile offers free and unlimited access with a simple possibility of download and local storage of a predefined map extent of an area of 10x10km for offline usage. Using a Swiss Map Mobile subscription, you store any amount of map material, depending on the available free space on the device. The subscription for one year can be purchased from within the application directly. More information on Swiss Map Mobile can be gathered from swisstopo.
Note: the application requires an internet connection in order to download map material. The connection can be established through Wi-Fi or a mobile network. On startup, the stored map data is automatically updated as long as a Wi-Fi connection and a valid subscription are established.
Continued use of GPS running in the background can dramatically decrease battery life.
