Amazing amount of info in an easy to learn and navigate package. The best features include the ability to select two similar species and then rotate them in unison using the 3D rotation tool (so that every similar/contrasting detail can be examined); and the bird sound tools, which include spectrograms and a 1/2 speed play option. There is however a small glitch in the 3D rotation tool that causes a few of the birds to rotate at a different orientation (90 degrees off) then the bird to which it is being compared. Even with this small glitch, this app is a spectacularly well-designed learning tool - and is also a lot of fun to play with!
Download issues. App won't load, download error as I am trying to load it on my new phone. Currently useless. Error is "An error was encountered during your download. Please try again". Tried over Wi-Fi and mobile data, no luck.
Bird calls don't play. Pictures are good, but frustrating when you can't hear the call at all. I've tried about 30 different birds and nothing happens when I try to play the call. Hopefully my donation will help improve the app!
Worth every penny--bought within 15 seconds of seeing it finally available on Android. The photos, 3D tool, comparison capabilities, and the many and varied vocalizations with descriptions, packaged in an intuitive and thorough interface are outstanding.
Best app ever, they can only improve by making a sparrow app just like it. I would by any app they make on birding n I think I own 95% bird aps n books.
If it would ever download the resources - by the time it's downloaded, warbler migration will be over.
Fixed issues with some songs not downloading. Fix to remove images from photo gallery apps on Android phones.
