Why continue to work only with the WM platform
There are now many good products for other platforms (Ios and Android)
Here are some examples
Maps.me - works nice on Phone platforms , gives you on-line and offline Off-Road navigation

Galileo - works on Ios , super app for on-line and offline Off-Road navigation
[Only registered and activated users can see links. ]
OruxMaps - works on Android (replication of Galileo) , super app for on-line and offline Off-Road navigation
[Only registered and activated users can see links. ]
and if you still stuck to WM and have problems to put your hand on Ios or Android
you got the old but still good enough OziExplorer CE
