i have the cabelas recon app and its pretty neat. A few features: ballistics chart, a map feature for bloodtrailing, compass, a ruler on the map that will measure distances (how far is it from any point on the map to another), moon phases, ability to pin waypoints on the map. I use the map more than anything, and there's more features that I've never used. Its worth a try. The only con is that it has crashed on me a time or two, but I'd buy it again.
