Useful App: Cheeky Fingers Piano Chords

I downloaded this app for free through a Starbuck promotion and I'm totally impressed.

I love almost everything about it and I think it could prove to be so useful.  Sometimes I just play a D major chord, or a major 7 chord, when I haven't yet looked at all the possibilities for "weird" chords.  Obviously it's good to figure out chords on your own, but I do like the idea of using this app as a "calculator" some of the time.  We all have moments where we're stumped or uninspired...so this is cool.

I'm really diggin' this app. I wish it had meter options and I'd love if the key names represented the proper spelling of each note in the "Key Name" display, but otherwise, this is a super useful app for the iPhone! http://cheekyfingers.com/
