Have you ever been listening to a song or have a friend playing some chords and want to know what key the song is in? This app could help.
This little helper can be used to identify the key a song is in via several methods
* Analysing live music via the devices's microphone
* Analysing a local audio file on the device
* A set of user-entered chords
All analysis is performed locally on the device so doesn't use your mobile data allowance.
The results of a scan can then be saved to be referred to later if required.
If there is a song that changes key part way through on the song detail page you can enter the chords or analyse via the microphone while you play that part of the song.
