All simply by waving your hands in the air. The era of gestural music is at hand!

A fun music toy

A fun app to play with, my only complaint is that sometimes it will get stuck on a note and I don’t know how to stop it other that shutting down the app and starting again (I’m using touch mode with the camera off).

OK, Theremin fun with banner adds

Just getting started & it looks like a lot of fun, but you must pay extra to remove adds! This is not mentioned in the description. BTW Developer is very responsive to your input.

Finally! Something useful to do with my phone!

I am happy to report that my phone just got useful with this new app. My own creepy theramin music is a bonus to have in my pocket.

I like that it remembered the settings i had programmed into it. The more i toy around with it the more stuff i can do. I like that you can choose between waving your hand or tapping the screen (manual vs auto). It's like a little secret bonus. Not just your ordinary Theramin. Well done!
