The lower frequencies are far too quiet. The range settings don't do what you would expect them to do... in fact I didn't notice that it did anything. As soon as I set the range the frequency immediately jumps down to 1 and sits there. It's good for simple, one frequency use, but nothing more elaborate than that.

Unless your contented with sliding up and down the frequency spectrum with 4 basic waveforms, you'll end up hearing more ads than any generated sound. Suggestion for devs: implement a minimum timer of 3-4 minutes between ads, rather than X taps between settings/options & Hold off all adds for at least 1 hour from 1st use. I was interested to explore settings and see what the app had to offer, but was hit with more ads than I could bear before I'd even been through it all. Ended up uninstalling.

Ads are too invasive, loud, and frequent. A complete waste of time. I couldn't even get to look through the settings and check back before I was blasted by several annoying ads.
