Therimax is a musical instrument designed for the iOS. Using the camera, a hand-held magnet, or the touch screen, Therimax allows you to create music without physical touch, without frustrating callouses or irritating music lessons, and without knowing a lick of music. All simply by waving your hands in the air. The era of gestural music is at hand!

Ratings and Reviews

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!



As a musician myself, I can appreciate the built-in scales and effects this application has in addition to the theremin effect. Tired of being ignored in the coffee shop by the barista, I use the therimax to garner attention and curiosity from the customers and staff of the locale. My Bela Lugosi mask and outfit only adds to my presence at the location. I plan to return in my favorite werewolf outfit as soon as they allow me to return to snobby Starbucks.

Amazing app


I've always wanted to play the Theremin, but never had the chance. This app sounds exactly right and when I use my fridge magnet I can even control volume along with pitch just like the real thing.
