Mapy.cz is far better than Google in case of Slovakia or Czech Republic. They have full coverage of high resolution pictures taken from planes and not satellites. Also these contain all the hiking, cycling and other routes. The native Android and iOS apps work great and support offline maps - you can download the whole map for a country with one click. Google Maps is unusable for sport or hiking because you only see a large green blob instead of the terrain with contour lines with altitude markings, all trails and roads and POI. Yes, Mapy.cz can't compete with car navigation, but everything else is miles better (and navigation on foot is better too).
