In preparation for the new FAA VFR charts we've added a new format to our supported list. We now support MBTiles format. So we now support single file downloads for most apps(MBTiles can be used on Orux instead of the native Orux format we need to provide as a zip)
So: MBTiles: Orux Maps, Locus, Galileo Offline Maps, Gaia GPS(Android Only).
RMAPSSqlite: Locus, Galileo Offline Maps, BackCountry Navigator.
We've also added documentation for BackCountry Navigator and Gaia GPS for custom tile based(Online, or in-app downloads) to our main charts page.
