Nice app. I was getting ready to chuck my old battery powered audio generator and went looking for an app. Haven't had a chance to test THD (that might vary by phone) but did test frequency response on an RMS volt meter. Response was absolutely flat 20 Hz to 20 kHz which says a lot about the iPhone 4 and 4S. The 0 dB setting gave -10 dB +/- 0.1 dB which is correct for an unbalanced output. Channels were balanced on two phones Four stars because the add ons are over priced and could be included as they are on other apps. 1/11/15 Add ons offered for free! I grabbed them. A very useful app. Added fifth star.

Needed a signal/ tone generator for my daughters science experiment. This works as one would expect and provides amble ranges. I'm no audio expert, as to the quality of output and ease of control is not an area I feel any comfort commenting on.

I've used test equipment that is not as good as this app. Easy to use and very low distortion output on iPhone 5 - 6.

Neat little app. Got it for no real reason, but it has made me realize that one of my ears is not as sensitive as the other at particular frequencies. I get a left-right shift as the freq. sweeps. Thanks for the add-ons.

I have only good things to say about this app. It was remarkably revealing to check out the frequency response of several different earbuds I own. Wow.
