I have been using these apps for 2 years. This year I added 2 more surrounding states. They have help me locate public land that you wouldnt even know existed and have given me the ability to request permission to landowners for hunting rights. This year they added some awesome updates that include the ability to see how many Boone & Crocket scored game have been taken in the area you are hunting. How cool is that. I highly recommend.
