I love it. It makes a few IDs that make me go "hmmm," but it's a pretty incredible tool. I've started to learn the less easy-to-remember calls, chirps, and bits. Wish list: a phone attachment to capture more distant sounds and a quick start button on my home screen to instantly start capturing calls. Could work better: a way to manually set my location when out of cell range. If there is, I couldn't get it to work (I didn't read any directions, see "out of cell range").

This is a wonderful app. I use the "Sound ID" all the time when I'm sitting out in my yard. I love how it creates a living list of the birds it's hearing, flashing a yellow highlight each time it hears the bird again. One thing I'd like to see is the ability to use Sound ID without making a recording. So it would just kind of be like a live field guide, but wouldn't chew up enormous amounts of space recording it all. Maybe the app already does this, and I just didn't see the option.

Amazing app! Correctly identifies birds with the touch of a button! It's user friendly and hasn't given me any issues! I highly recommend it for anyone, new to birding and experts alike! Having so many different ways to help identify birds really helps depending on your situation. If I went on a trip with my camera, just have to do a quick scan. If I'm out in a walk with my family, it will identify all the birds we hear as I record. I love that it highlights the birds whenever they make noise!

Sound ID is better than over, with additional birds for the United States, Canada and now the common species of Europe, northern Africa and the Middle East! Record the birds you hear, and watch real-time results show up on the screen to help guide you to the correct identification.
