Display the map you like
With Maps Viewer you can display your personal maps on mobile.
To do this add your url or drop your mbtiles in the resources and it's done.
I add features according to my desires without necessarily writing it here.
Don't hesitate to test it especially if you have a Garmin or if you like maps.
The project is open source if you are interested in contributing.
