Overall review ****
If you're like me and have trouble sleeping or concentrating in noisy, disruptive environments, you'll love Ambiance.
It's a .99 cent application that quite simply plays many soothing sounds and variations of white noise. When I have trouble sleeping, I'll often turn on a fan for the white noise, but this application offers a much better option. It plays 14 relaxing sounds: birds, blue noise, clock, creek, crickets, fan, machine, pink noise, rain, violet noise, waterfall, waves, white noise and wind. I have found all of the sounds to be realistic.
The application also includes a timer, allowing you to have the noise turn off after anywhere from 1 minute to 24 hours.
My only complaint about the application is a relatively minor one. Some of the sounds seem to have been created a different volume levels. So, as an example, the white noise can be heard clearly when the iphone is set to a low volume, but the machine noise can barely be heard at the same level.
Pros: Cheap, simple to use, multiple soothing sounds
Cons: Volume levels seem to vary from sound to sound
