Theremin I/O Reviews

Awesome simulation!

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

Issue with calibration

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

Cool gestures

It's a fun little app to experiment with camera gestures like air vox

~ By redindian75

Very, very cool.

Not only is it sensitive to your hand motions, but it calibrates well for light conditions. Also, lots of voices and harmonic settings. Very nicely done.
