All I've used for the last five seasons elk and deer hunting. My current phone is kind of sucky but it's the phone not the program. Only pitfall I have with the program I have is every time I upgrade phones, I lose all my maps and waypoints, maps are free and easy to download, waypoints cost a lot of blood sweat and tears, I'm going to write them all down next time I upgrade phones and maybe start a file on the computer. It's priceless to have a large touch screen GPS for less than thirty bucks that has private/public property boundaries and GMU boundaries. I use Backcountry Navigator, you download maps at home and you DON'T have to have cell service in the field.
