Hey guys I just got a new app for my iphone that works pretty good. It is called topomaps+. You don't need service or internet for it to work if you cache the map before you head to the field. You just zoom to the area you will hunt and then let your phone cache the data and you are good to go. I have been using it off and on for the last month and haven't had any problems with it so far. It does not have landowner info, but usually where I'm elk hunting I'm not close to private land anyway, but if I am then I already know the boundries. Worth taking a look in my opinion.
