Noizio!

Noizio is an app that will drown out the noise of the street and allow you to concentrate on the work at hand, increasing your productivity. On the other hand, it can also set the mood for a romantic evening or lull you to sleep, ensuring that you will dream soundly all night long. Use it to help you work or study, or allow the sounds of this app to transport you to a cozy camp fire under a full moon or to any other place you can imagine.
