Etheric Synthesizer (EtherSynth) is a theremin-like synthesizer application for Android platform, which allow you to play otherworldly melody by swiping finger on the screen. Though It does not closely imitate a real theremin as Etheric Synthesizer uses only one finger to play.
It currently supports monophonic note playing with configurable waveform, frequency scale, control area, and control orientation. Basic recording function is also included (WAVE format).
