Coffitivity loops coffee shop sounds to help those who work better with background noise.
Minimally invasive: Coffitivity resides in the upper menu bar and stays out of your way.
Volume control: Coffitivity's noise level can be controlled separately from your Mac's main system volume, so it doesn't underwhelm or overpower concurrently playing sounds.
Lack of music: It would be nice to have more variations, such as background music or cafe ambience from different regions of the world.
Coffitivity's only purpose is to create ambient coffee shop sound, and it delivers. If you don't feel like walking to your local bean brewery but can't work without the background noise, then Coffitivity will bring the sound to you.
