I have used the BirdsEye app and it is all you have said it is. I have in fact used it on trips. It was very helpful on our early May trip to SE AZ. It helped us find a red-cockaded woodpecker in LA earlier this year. I find useful the known hotspots (i.e. NWRs, "Gaddy" in TGP, etc.) which shows me what has been seen and how recently for a particular spot.
