Very annoying that it would play video ads with loud audio. Deleted.

I use it to demonstrate resonance in an air column in 9th grade physics. Very convenient.

There seems no way to increase the volume or amplitude which a glaring design error. The sign out selection is impossible to access long enough to actually sign out. Selection of controls seems awkwardly designed and counter intuitive.

I use the tones in this app for when I'm sleeping at night and I've gotten better sleep ever since. Definitely worth purchasing!

This is great. Hooked up to 500 watt Bluetooth speaker and use it to shut up the damned barking dog next door.
