I can not drive (yet) and I get lost pretty easily. So, I need a simple navigation app (I like the gmaps look, just roads, no fancy colors and things), which includes ALL bus/tram/metro/train (yeap, all of them) stations of greece, their schedule and navigation through them. I NEED it to be offline, otherwise, I would use my favorite gmaps. Cellural data here cost A LOT (I have only 60MB/mo). I've tested nearly each and every navigation app out there. I don't care about the cost, but being free is a plus, especially open source. I can extract the points of bus stations (I think) from the maps provided by greece. I can also extract the schedules, but i don't know in which format.
thank you! I've searched the whole web and I found no answer...
