If you want to listen to an audiobook, Audible is the number one source. Though, the app was never great on Android. It wasn't terrible, but it didn't have a strong Android aesthetic and the layout was strange. With the version 1.5 update, that's a thing of the past. The app looks excellent now, and there are other improvements too.
The new UI is still a dark affair, like the old one. The colors are distinctly Audible, which is actually a nice look. It's also got a fair bit of Holo (#YOLO) going on. Here's the full changelog:
- Beautiful new design
- Improved navigation
- Simplified library management
- Chapter-level progress bar in the player
- Improved stability and performance
Audible's app is free – the books not so much. It will cost you a few bucks to subscribe and you get a set umber of titles each month. Or you can buy books outright, but they're pricey. Check out some screens of the old UI below to compare.
