MacStories:

An ambient noise app’s most important job is providing a variety of sounds that can evoke a soothing sense of calm, and offer environment control. The App Store is full of apps that accomplish this purpose, and a new one’s being added to that roster today: Dark Noise, from developer and designer Charlie Chapman.

One chief advantage of Dark Noise over its competition is that out of the gate it’s the best of iOS citizens.

We occasionally use a noise generator called Noizio for its simplicity – we only ever use the “rainfall” setting – but if you need something more, check out Dark Noise.
