We got this review for iBird North in the app store today:
5 stars on Jul 12, 2011
I have been using this app for for over two years now and couldn’t be happier! My friends are so impressed how I can ID so many birds just by their calls! My recognition ability has improved ten fold! One suggestion though that would improve this app to the point of astonishment would be audio recognition. Simply point the phone in the direction of a call and the app would ID the bird based on the call (just like “sound hound”). That would be amazing! Thanks for everything!!
Even with all the exclamation points its an awesome review. But the part about audio recognition got me to wondering how many other birders would like such a feature? And do you think it would be hard to program into an iPhone?
