Great for reference
To begin, this app is not a topo map app. I use this in conjunction with a topo map app, not in place of one. It is an app which enables you to have copies of the park services maps available for preplanning or on the trails once you head out. It is really convenient to find a park map on your iPad to plan the hike you want to do and to familarize yourself with the trail as it will look on the park service map prior to heading out. Further, the map is downloaded to your iPhone, which means that it is there for you even if you do not have service. We normally take the park service map with us (old habits die hard, I guess), but there was one time when we were on a long loop hike (12 miles) and about two thirds of the way we realized that we left the map in the car with no cell service (and the topo app hadnt downloaded the map). We were thankful we had the map downloaded into Maplets. We found our intersection and headed on our way. The GPS feature is great and helps recalibrate you if you need it.
