Offline Maps


In general, there are two ways to use map material in Routes. Online, a permanent internet connection is necessary to download on demand map tiles. And offline, here the map material must be pre-installed in order to navigate without an internet connection.
Routes basically works offline, even if no underlying map material is available. You then just follow the route line without map information. But Routes always downloads contextual map parts (on-demand) if an online map is selected and if an internet connection is established. Alternatively, you can use an offline map with pre-installed map files in *.map format.


Routes uses MapsForge in conjunction with OpenStreetMaps. There are some vendors that offer pre-built maps in *.map format. 

DOWNLOAD: We recommend downloading the offline map material from: OpenAndroMaps
These maps fit perfect to the Map Style Elevate/Elements map theme by Tobias Kühn that we use in Routes.

But it is also possible to download *.map files from other sources.

RESPECT: Please respect the terms and conditions of all vendors.


If you have downloaded your desired map files from one of the vendors listed above, go to “Offline Maps” in the settings of Routes. Here you can directly import and remove maps in *.map or *.zip file format.

MEMORY: To import large maps, you need enough memory on your phone. Ideally ‘2 * map size’ because we copy your map to the internal app data folder.

To finally navigate and record offline, select one of our offline “Map Type”.



  • In case there is not enough space left on your phone to import the map (map size x 2) or something else did not work well during the import, it is even possible to move the map manually on your phone to the Routes import folder: “/YOUR_STORAGE/Android/data/de.flosdorf.routenavigation/files/osmdroid”.
    • If you have downloaded a *.zip file and copy/move the maps manually into the import folder of Routes, you must first unzip the *.map files contained in the archive.
  • Routes is installed on SD card by default. If not, you need to move Routes from device’s memory to SD card. As this is manufacturer dependent, please check the internet for information on how to move apps on your phone to the sd card.
