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?

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!

My only problem with this app is that the frequency control buttons are cut off the side of the screen. It needs to be fixed so that all buttons are visible on all devices. at the moment I can change the waveform but do not have full control of the frequency.

most of the buttons are off the right side of the screen, making this app completely useless.
