Coffitivity OSX App
Coffitivity is an online service that provides ambeint noise to mimic that of a coffee shop. It's been shown to increase focus and productivity. But browsers have some limitations when playing audio, so I built a native OSX app for a better experience for Mac users.
The app has a simple interface that all takes place in the menu bar. You can have it launch on startup, and even set a preference so that just clicking on the icon will stop and play the audio. It has been featured in several publications, and eventually rose to be #11 overall in free apps.
