Great app, BUT

This has been an invaluable tool for birding, and even though it takes up an enormous amount in of memory on my phone, I still keep it, deleting other apps if I need space. However, updates take forever, and the latest one will not install on my iPhone 6. Very frustrating. Works flawlessly on the iPad Air, but the iPad is too large to carry around with binoculars and camera gear.
