Phone Theremin
Touchscreen Theremin
$0.99 · Designed for iPad. Not verified for macOS.
Phone Theremin transforms your touchscreen into a fully expressive theremin. Two-zone control lets you play pitch and vibrato simultaneously.
Turn your iPhone into a real theremin — the haunting electronic instrument that plays without being touched.
Phone Theremin uses your screen as a two-zone controller. Touch the left panel to activate sound and slide up and down to control volume. Use your right hand on the pitch zone — slide up for higher notes, down for lower. Move horizontally to add vibrato depth. Lift either hand to silence it, just like the real instrument.
