Mobile and offline use
MTL Explorer works in your phone's browser. The bottom toolbar has GPS, Map, Filter, and Planner; the other tools are under More. You can add it to your home screen with your browser's install option.

Show your position
Tap GPS and allow location access in your browser. This only works over HTTPS. MTL Explorer shows where you are but does not record your activity.
Use it offline
Offline, you only see what this browser has already loaded. Before a trip, open the map area and tracks you need while you are still online. Route planning, search, and photos that weren't loaded before won't work offline.
Offline maps on the server are different: they still need a connection to your server. Some map layers, like 3D terrain and trail overlays, always need the internet.
Clear & sign out in Settings → Session removes the saved data. This guide is also available offline once the app has been opened.
