I just updated my review after updating this application. Ive been using this app for over a year and the functionality alone is worth the price of admission. Being able to add bookmarks, etc is great. I have been looking for a good audiobook player for a long time and this is the best one that I found. This is called the freemium model of business where the app developer gives you a taste by allowing you to add three books and then if you want to continue you pay to upgrade to add more books. From what I understand the app store doesnt have free trials although they could do a light version of the app. Perhaps there should be a way to back up bookmarks and be able to restore them if that is an issue. I didnt see any backup options within this application so.... This app works on both my iPhone and iPad. It keeps your place which is great and you can even add bookmarks. I emailed for help and they got back to me super fast to help answer a few questions. This app developer updates this app often which means they work hard on making this a better and better. I have been using it for a long time. I did find they have a website that teaches you how to use this app. Just tap on the star button within the app on the bottom and tap help/FAQ. It is working great I found I can add my own artwork to my personal audiobooks which is cool. I found swipe gestures to skip ahead back and forward etc. I suggest to read their online manual as some of the things are hidden like the swipe up for the left side I had to read to figure that one out. I purchased the in app purchase so I can add more than 3 audiobooks. I used to use an app called bookmark which was awesome but they stopped making that app so I have been looking for a while to find one I really like. This is it. Just take the time to read the help/FAQ as it has a lot of great features that may not be obvious. By the way if you have a lot of CDs that are audiobooks, there is an app on the mac called audiobook builder which is a great way to rip the disks, and make an audiobook. It will even import to iTunes and it will show up as an audiobook and not music. You also can make audiobooks out of files too. I think it may be in the Mac App Store and also on the splasm website.
