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.
