Awesome concept! Could you maybe work on the controls for frequency? I can only see options for +-1k and +-10k on my S4, but your screen shots show much finer tuning options. Thanks for your work!

Works, but... If you need an arbitrary waveform generator, this is one of your few choices. It certainly works, and while the GUI needs a bit of tweaking, it does its job as well as can be expected from a cell phone. On an oscilloscope, I see a lot of ringing. The square wave isn't particularly square, and the sine wave is a little fuzzy. Things quickly get messy after 1khz, with the arbitrary waveform becoming nearly useless. But is this the app, or are we asking simply too much from the audio output of our phones?
