This is my first pick because it’s the audio book system my local library uses. I can check out audio books and play them on my phone now just like I can play them on my Nook eReader.
Audiobooks from Audible
This app has its own store and a great selection to choose from so you can grab a new book on the go. Try it out for long car rides.
Stream or download books – good option, that streaming. Books take up space on your phone’s memory, and while streaming may run up your data, it’s great on Wifi.
Ambling BookPlayer Personal
This is the mid-level version of Ambling BookPlayer – there’s a freebie and pro version as well. Nice interface, good selection, and plays nicely with bluetooth in your car audio.
