DO NOT BUY GAIA FOR ANDROID! I wanted to like this app and used it for a couple of weeks with success. Then, lately, the app completely failed multiple times The screen on Samsung Galaxy suddenly and inexplicably shows no map at all, just black screen with a colored line, presumably the route. This is REALLY dangerous if you're counting on it in a whiteout or off trail suddenly the map screen goes black and you have no idea where you are. And, yes, I've tried every fix the company recommends and that you can find online multiple times with no success. Stay away from this product until they fix it. Go with All Trails instead. I have no financial interest of any sort in either app, I just don't want folks getting lost or worse by relying on GAIA GPS with an android phone.
