Topo Maps+ version 4.5 now has the 2016 US Forest Service topographic map. Like the USGS topo map this map has the backcountry features you need while hiking and backpacking. It is an updated topographic map with cleaner lines and labels.
The US Forest Service map does not cover all of the US. This video shows you how to use Topo Maps+ PRO to create a continuous US map and how to add hill shading.
You can switch to the USFS 2016 map by tapping on the mac icon in the upper right corner.
