Very basic but with a unique feature The app lacks the common white/pink noise source, but when generating sine waves it can generate left/right signals with a defined phase offset. This is very useful when debugging audio equipment, e.g. for creating symmetric signals. Also the trim seperately labeled in dB for left/right is handy.

Works great on my HTC One (m7) Unlike any of the dog whistles, this app actually does produce up to 20kHz from my phone's speakers. No fancy presets, but great basic functionality. Wish it had a frequency sweep function.

Nice Job I've got a sixth grader starting to learn about waves. This app provides a great opportunity to demonstrate frequency, amplitude and constructive and destructive interference (by phase shifting the right and left stereo channels through a Bluetooth-enabled speaker). It's not a stretch to see the brilliance of noise canceling audio headphones. Again, bravo to this app creator!
