I have no access to change sounds. The bottom shows up for half a second and then goes blank. Where do I change sounds? Pretty cool how it works though. It’s awesome. Just love to have other sounds.

The GUI is top notch. Way above other apps that try to mimic the theremin. Very customizable and well worth the small cost.

I checked, and my phone allows this app to use the camera, but it could never calibrate.
