Charlie Chapman, developer of Dark Noise, my favorite white noise app on iOS, has just released a version for the Mac:
Taking advantage of the Mac platform, a new innovative "adaptive toolbar" UI allows you to shrink your window into a Mini Player to keep Dark Noise quickly accessible while taking up very little screen space. Dark Noise for Mac also features full menu support with keyboard shortcuts to feel right at home on your Mac.
All of your favorite Dark Noise features are here including timers, custom mixes, widgets, and multiple themes. And with iCloud syncing, all of your custom mixes will automatically be available on your Mac.
Dark Noise is a must-have on the iPhone if you love falling asleep to the sounds of thunderstorms or crackling campfires. For me, I plan on combining the Mac app's library of soothing sounds with my favorite background music channels on YouTube (the links to which you'll find below) to help me focus during my workday.
