Hushaboom

A simple white noise and ambient sound app. Seven sounds you can mix together: white, pink, and brown noise, plus ocean, wind, rain, and trees. The nature sounds are synthesized rather than sampled, so nothing loops. Each sound has its own level and its own controls. Set a sleep timer and it stops on its own. No ads. No tracking. No account. No network code at all. Runs on iPhone, iPad, and Mac.
