MAPS.ME is the best one by a pretty fat margin, I'd say. Map viewing is wonderful, the best I have experienced on Android. It's very fast and super detailed.

MAPS.ME is the best one by a pretty fat margin, I'd say. Map viewing is wonderful, the best I have experienced on Android. It's very fast and super detailed. Routing has some issues. The estimates are way off, routing by bike means road bike (not MTB) and the voiceover speaks too early or too late.
