I just came in from an overnight in which I got to play with GAIA a little bit. So far I think it’s a better product than Backcountry Navigator. Granted, I’m running it on a better phone than I had before, but it’s still more intuitive for this fairly non-tech outdoorsman. I’m impressed how quickly I can get a GPS fix with it, leaving it off to save batteries but getting a location fix, dropping a waypoint, or finding any information I want to know within seconds of starting the app.
In my opinion, Backcountry Navigator had a fairly roundabout way of downloading and installing map tiles. With GAIA I had everything I needed saved (all of Angeles National Forest) in a minute. Fast enough that I can swap out maps at-will before a trip to save memory if needed. I never felt BN was this user friendly. Overall, I’m impressed with the interface.
