Dont delete if you got it free!!!
When I couldnt change back to notes C, D, E, etc. after using sol-fa scale, I deleted the app and reinstalled to reset it. All of the nice features that had been bundled with the original purchase (was it free through Apps Gone Free?) were gone. Stupid app would not honour my original free acquisition with all the bells and whistles that I had. Sorry folks, Im deleting this one. Dumb pop up window dogged me at every push of a feature button.
