alt Hacker NewsFinding MapQuest on the PlayStore was a quest all on its own. More specifically, it does not exist on my PlayStore, and I had to install it on my phone remotely through the browser PlayStore.
Review wise, it sits firmly at a single star, so it's possible that Google burried it, although I would not put it past them to rig things.
Recommend you instead use something like OsmAnd. Mapquest pulls data from OpenStreetMaps - might as well use an open source application.
