This is the review I posted on the App Store:

I hate rating free apps with one star, but this app is a poor reflection of an otherwise good service from Audible.

1. Downloads are slow
I’ve tried for two days to successfully download “The Girl with the Dragon Tattoo” from my library. First, it takes an hour for a 250MB part 1. The same download on the same broadband from my Mac takes 15 minutes.

2. Downloads are incomplete or corrupt
Three times, the app downloaded an incomplete part 1 and the fourth time the book was corrupt after chapter 30. The app doesn’t seem to support IOS4’s ability to download in the background. Plus, there is no way to resume a failed download! You only have the option of deleting and starting over.

3. Audio playback isn’t implemented correctly
IOS4 apps like Pandora and Podcaster play audio that can be paused with the iPhone headset, even when the phone is locked. This app doesn’t do that, you have to use the play/pause buttons on screen which forces you to unlock the phone just to pause playback. There is an option to force the screen to stay on (never lock), but this drains battery very quickly.

4. Playback controls are inconsistent
Audio scrubbing doesn’t work properly. In one case it brought me back to the beginning of the whole book. Chapter skips are inconsistent as well. I skipped from chapter two and ended up on chapter five. Very frustrating.

5. Bookmarks are local to the device
If you remove the book, you remove the bookmarks. They are not sync’d to the cloud. It sure would be great if I had to delete a book for space reasons. Then, when I was ready to read it again, after downloaded, the bookmarks were there.

Based on these problems, I’m going back to listening to Audible books using the iPod app. Audible, please fix these issues! This app has great potential.
