Working in an office or even at home takes a lot of concentration, as there are noises and movements happening all around you. One way of being more productive is to use background noise and this is where Noisli by Stefano Merlo comes in; it is an app that produces background sounds. The idea is that these sounds drown out other sounds such as people talking on the phone etc, the colours are supposed to help you when doing particulars tasks, such as blue is good for creativity and red is for tasks that requires the user to be more detailed. The Noisli webpage is simple enough with icons covering the sounds that are available; there is a volume control, which comes in handy while you are testing them out.
There are wide range of sounds available including; Rain, Thunderstorm, Wind, Forest, Leaves, Water stream, Seaside, Water, Bonfire, Summer night, Fan, Train, Coffee Shop, White Noise, Pink Noise and Brown Noise. While the background changes colour right through the pallet. The web based app is a great way to see if it is for you before paying the iPhone app. The Noisli app is available free through your browser or as a Smartphone app for your iPhone; the bad news is it will cost you just $0.99 from iTunes.
