Android: Noisli has caught our eye as a quick an easy way to put on some background noise on the web, iOS and Chrome. Now it's finally arrived on Android as well. Once you open the app, you'll presented with a selection of simple icons. Tap as many as you want to create the soundscape of your choice. You can add sounds like wind blowing, water running, fire crackling or even three forms of basic white noise. You can also adjust the volume levels of each sound independently.
