I call this app the firefinder. When I get the coordinates for a wildfire, I enter it into locus and download the topo and sat maps of the area before we get out of service. When we find ourselves hiking to a fire, this becomes incredibly useful. This app is leagues better than anything else I've found, including any dedicated gps. The only reason I still have my handheld gps is because my phone won't last more than a day without a charge, and the battery can't be changed.
