I like this app for basic purposes of finding a quick ID of a bird. Also it does include good pics and songs and calls. However, I find the birds that come up as options are limited with their descriptions - sometimes causing it to miss the bird you saw. It asks you to share a sighting. I try but if the bird you saw doesnt show up on their ID description you cant share your sighting. I did find it on their overall list even though it wasnt IDd but the list wont send or allow you to choose a bird as a sighting. If you want a very basic bird ID it is useful.
