Audible is my number one time wasting app when I can wear headphones or when I am traveling. I say time wasting, but in reality it's not a waste of time at all.
With audiobooks I can learn or simply be entertained by fiction while I am doing other things. I listen to Audible in the car, in the shower, while doing yard work and in airplanes. Wherever I can, I am listening to Audible. I love fiction, but don't have as much time to read as I used to. With Audible I can combine activities and it even makes shopping enjoyable.
The Audible app is free and you can download individual books or sign up for a membership that gets you a discount on books. If you sign up now you get two free audiobooks to start and you can see if you like the service.
