iOS map app that can load MBTiles tileset Are there any good map apps that will allow me to load the map from an MBTiles tileset file?
I'm looking for something that will allow me to use the map offline while hiking.
I recommend you one of these :

Guru Maps, its free version allow you to load 3 offline MBTiles. Their paid version is quite expensive - 50$ but the app is well-made.
OpenMapTiles, if you want to use OpenStreetMap vectors only.
MBTiles GPS, the app interface is basic but it's free.
MapTiler Mobil‪e‬, I've never tried it but I heard great feedback about it.
