This app has been out for a while now, but I only started using it recently due to the fact my iPod died.
First the pros. I love the fact it has a 3X speed. The iPod app on the iPhone only does up to 2X speed. It also let’s you add bookmarks. Another nice nice feature is the sleep timer.
Now for the suck. Even though you can scroll though your all of your titles, you can not download them without wifi. There is also a nifty rank system that tracks your hours, but it only track the hours in the app and not the hours you have in your library.
If you have an Audible account and an iPhone, it’s a must have free app.
