I use Map Plus (iOS). It's like google
mymaps but better (and you can import all of your google maps and just about any other map into the program). It's by far the best I've found so far. The only disadvantage is that there is a bit of a learning curve. I still don't know half of what this app can do.
I don't know if it is offered for android or not, all my stuff is apple.
Edit: Perhaps the greatest advantage of this app is that there is no size limit. Mymaps only allows 2,000 points per layer. If I hit a limitation on one of the google map programs, I just transfer the map to here and I can see the whole thing.
