4WD Maps - Offline Topo Maps

4WD Maps - Offline Topo Maps is a navigation app for people who want topographic maps without relying on a connection. By our assessment, the useful part is the offline map side: it suits route checking in places where signal is weak and the terrain matters more than street names. The trade-off is obvious too, because offline topo tools can be only as good as the maps loaded and the screen they are shown on. In practice this kind of app is about planning, zooming, and reading contour lines rather than tapping a turn-by-turn voice prompt. It sits closer to field navigation and outdoor map readers than to the slick car nav apps that try to guide every turn. The title is blunt about the job, which is helpful; it also means there is not much mystery about what it can and cannot do.
