This is a good app when you can get it to work. Seems like the people designing this app never used a paper map before - the most basic things you would do with a paper map like save/mark locations on the map with your own name are painful. Recently dropping a pin has stopped working. Google search about this is useless - gives me tons of directions for how to drop a pin (all the same and not working for me). I'm ready to pay for a real mapping and navigation app that works....
