Ever wondered what the key of a song being played is? Wonder no more! Just use the built-in piano keyboard to play along with a song's melody. As you confirm notes that coincide with what's being played, KeyFinder will narrow down the number of possible keys the song is in.

Several features include:
• monophonic playback (use KeyFinder as a soloing piano!)
• no distortion, clicking
• red LEDs to mark off improbable notes
• toggle between Major and Relative Minor keys
• use Keyfinder while iPod music continues to play
• HIDDEN easter egg! (There's an undocumented feature)

Can't play minor scales in Ref mode though...

Not very good


Hard to use, very unclear

Good idea


Might give it a higher rating after I use it more. Only tried it a couple of times. I like the idea of what it can do. Would be better if could control volume of app separately from iPod music. I find I can't hear the keys well when tapping them and when I turn up the volume, the song that's playing just gets louder also.
