Nice, but I prefer to use PC :)

I have an app for that on my tablet. Several types of waveforms such as sinewave squarewave sawtooth etc with lots of presets as well as custom tones. Also has white and pink noise as well as sweep generator. I think it is called simply Audio Test Tone Generator from the Google Play Store. It works great.
 
I have a similar app on my phone. I made a harness to adapt the headphone jack to a 4 pin cobra. I'm just a shade tree radio tech but it seemed to work well with my uniden 68 tone generator.
