Thinlyn and other people seeking support, don't post a review, instead contact me on http://mp3book.tumblr.com/ and I will help you in any way i can to successively use the app.

Thanks!

This is an automatic bookmark app for audiobooks. Bookmarks are created automatically and kept for each track.
You can put a collection of tracks into a folder, which constitutes one audiobook. The application will then remember the location last listened to in each track, and the last track listened to in a audiobook, allowing you to easily find your place even if your audiobook is made out of many parts. It will also keep track of multiple books at a time in case you want to switch between books.
Please note it will not work with DRM protected files like ACC or Audible .aa files. You will need to convert those to mp3 in order to use with this app.

The application works off the iTunes library, so follow these steps:

1. Add book to iTunes as mp3 files (or any other ios supported unencrypted format).
2. Sync To iPhone.
3. Open the app and press the + button to add.
4. Select all the tracks from ITunes library to be in the book.
5. Press Done.
6. Click the newly created book in the list to start listening.

I have been using this app myself every day on my drive to work for 6+ months. It is very stable already and I will continue to improve.

Please don't hesitate to ask me for support before leaving a bad review I will be happy to resolve any issues you find, just follow the support url to ask any questions.
