As someone who spends a lot of time outdoors, I can reliably say that the most important feature of Topo Maps+ is its support for offline usage. You can be deep in the woods, far from any cell signal and still use the app to navigate from waypoint to waypoint. Before you hit the trail, just remember to download the maps in advance. You can then use the iPhone's GPS and compass along with the maps in the field. ... (See full review here.)
I love being able to trace out my route before my trip, having the ability to create waypoints along the way, and measure how far the planned route is. I have a waterproof case for my phone so on my last trip when it poured rain unlike the other guys with paper maps I didn't have to worry about constantly pulling the map out of the case and folding it every segment of the trip. I'm even looking forward to using it while hunting. I highly recommend getting this app if you do anything outdoors.

I absolutely love this app and highly recommend it! My brother and I were out on a backpacking trip in a place with no cell phone reception and the trail was covered in snow! This app was able to use GPS and topological maps to tell us exactly where the trail was at in an amazingly accurate way! It told us to walk 10 feet away and sure enough we soon found the trail. This app rocks and I highly recommend it for any outdoors enthusiast!!

The relief shading on top of the USGS Topo Maps is beautiful and really makes these maps far more useful than they are by themselves!
