Bluetooth ?
Response from developer
I have never been able to duplicate this problem and no other customer has ever contacted me with this problem. I have no information regarding the device used or the operating system. The email address on my website is, and always has been, functional. So, this review doesn't make any sense to me.

Pmeo12331 was correct. The first release had a bug that caused the app to function as if it were the Treble Clef. After reading Pmeo12331's review the app was taken down, fixed and re-released in late Jan. of 2014. Since then the app has functioned correctly
