Aviphone

Learn some of the more common birds' song, using 3D sound to make it a fun experience.
The app was inspired by trying to spot skylarks singing in the sky.

NOTE: The Listen & Locate game mode requires a device with a gyroscope.

Two game modes:
* Listen & Locate - use headphones to listen to bird song and try to locate where in the virtual environment the bird is.
* Quiz - listen to bird song and try to guess which out of several birds the song belongs to.

You can also look up birds in a list to find out more about them and listen to their song.

You get five birds for free and can buy more in the in-app store.
