I do enjoy myNoise, but I find their mobile apps to be usability headaches a lot of the time.

Just use the website. Add it to the home screen (on Android) and it functions like an app. The only downside is that it requires Internet to load the noise generator.

Stephane Pigeon of myNoise.net made the website himself, but hired out the app development.
