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)

Needs more key support

Good attempt, but it doesn't have things like C sharp major and C sharp minor. Also it's a little slow in responding to the touch. This would be worth paying for if it was seeing every key and faster, I'd pay 2 dollars for this if it recognised all keys. Cheers.

Thank you so much!!!


No more I need to carry an old A4 sized chart around, just my phone and this app!

Edit: Now... What is the undocumented feature?? :)

Fairly good


Good application, I havnt checked all the keys to see if they work, but up to now it is correct! For free it is good, but I wouldn't pay money! 6/10.
