Theremin I/O App Reviews

Functions perfectly! The light sensor functionality is virtually flawless and the sound presets sound beautiful! It's really cool controlling the sound just by moving your hand closer or further away from the iPhone. You can also manually adjust vibrato and delay for added customization. In addition, they give you around 70 unique scales to choose from, and an option to just use the whole keyboard! It's one of my favorite apps!

The sound is pretty authentic, but a real theremin isn't zippered.

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.

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

Too cool try it !

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

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.
