I read several reviews before buying this app. I have also downloaded 5-6 apps that claim to be helpful out on the trail. None of those come close to this app in terms of functionality and reliability. Even though this app takes a little while to figure out, I tested in on a long weekend hike in an area that is in the middle of nowhere with no cell signal whatsoever. We backpacked and hiked in a mountainous area with no trail markings. The GPS combined with the topo maps were like a Godsend for this hike. I loaded several waypoints using coordinates from Google maps into this app priori to our trip and it saved our day by helping us stay on track. This is a MUST HAVE app for all backpackers/hikers. The iPhone 6+ upgrade was perfectly timed for our hike. Well done and thank you!
