I was just simply looking for an app that would help me transpose a song from one key to another. This was exactly what I needed. If you need more intense work done to a song find another app, but if you are just looking to change a key, this will work just fine. I was pleased.

I found this after trying several other free transposer apps. None of the other ones have the option to choose a minor key!! This one is nice and simple with flexibility for any key. Thank you!!

I was looking for something where I could transpose a series of chords and glance at and play them. This forces me to jump around to see what each transposed chord is. It also make me figure out all but the basic seven chords. Got a VIIb in your song? You'll have to change the diminished to a maj, and then flatten it, all in your head. Please update to create what could be a useful app.
