OsmAnd+ is the full version of OsmAnd: the former is a paid app on the Google Play Store, the latter is free but is limited in features. However, because OsmAnd(+) is open source, you can build it from source code. The F-droid store of open source apps does this for you! Here are the steps to install OsmAnd+ this way:
- Go to f-droid.org and download the .apk of the F-droid app
- Click the file to install: your device will ask you if you want to install an app from an unknown source (your browser). It will pop up the settings to change installation permissions.
- Once installed, open F-droid and search for OsmAnd. Click “install” and you will again be asked about the same permissions, but now for the F-droid app as a source. Fortunately this is the last time you have to change these permissions!
