Will I need data to access FATMAP on the mountain?

Streaming maps on the FATMAP app requires an internet connection.

However, with the FATMAP Explore and FATMAP Offline Access subscriptions (both available in the FATMAP App) you are able to download as many areas as you like on to your mobile device (we recommend downloading over WiFi). When you have done this, you will not need mobile/cellular data in order to use FATMAP.  

GPS functionality does not use data but to update the real-time data information, such as the snow layers and resort status, updating your offline maps and updating the app itself, you will require data.
