Awesome Backgcountry Mapping App – Topo Maps+ Review

I use Topo Maps+ on my iPhone for my backpacking trips into remote regions. The ablility to add tracks from Google Earth (KML) is awesome for adding routes that don't already exist in the OpenStreetMap trails layer. Also, the battery usage is much lighter than many of the alternatives, which is critical when you are in the backcountry.
