Audify will automatically read your notifications to you when you're in the car.
If you are ever in a situation where reading your notifications might be annoying or dangerous, Audify will read them aloud to you. The app works by speaking your notifications through a connected speaker or (wireless or wired) headset. The thinking is that when you have a headset in, it's probably not a time when you want to be fumbling around for your phone. (Let's say when you are in the car.)
