About this app
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.
