Today I found about Organic Maps[0], and it seems like a viable alternative to Google Maps, albeit with some annoying quirks.

It is offline - meaning you download the areas you are interested in first, after which all the data is available fully offline (including stuff like directions, metro maps etc). The interface takes a bit to get used to, but the biggest let down is the fact that you can't edit a route in the route planner - you need to start all over again (selecting start/destination, no way to modify either).
