Best birding app

I have pretty much all of the main birding apps for my phone. This previous version of this about was my absolute least favorite of them all. However, since the redesign it has now become my hands down favorite. Very well done.

One thing I feel that is missing is filtering by species. I find it helpful to be able to narrow your search by species when trying to identify an unknown bird.
