Ratings and Reviews
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.
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!
