Duke, I think your stat is incorrect if you think 99% of people don’t care about the chapters. This thread wouldn’t be 22 pages long if people weren’t concerned about them. There are reference books that divide subject matter by chapter which people refer back to & would thus need chapters. Others may have different reasons for wanting chapters. Even if people don’t care about chapters & just wanted to remember where they left off, every audiobook app I’ve tried (including the built-in Music app) remembers your location where you last left off and most of the apps have the bookmark function - that is the standard these days (except for the Music app). So it seems you’re making most of your pitch based on the bookmark function, which Apple’s Music app doesn’t have, but most other apps do (free ones too). I’d even say it’s kind of insulting if you’re telling people in a forum who are complaining about the lack of chapters to buy your app and then tell them to manually place bookmarks for every chapter. Really? And an extra charge to play podcasts?
Most of the other apps also have all the features that you mentioned but they’re free. For example the Audible app skips backward/forward by customizable amounts (not 99 mins but who wants one that long anyway), remembers your last location, creates bookmarks, keeps the dates/times of those bookmarks, and jumps to whatever segmentation is available. In the last one, the difference from your Bookmobile app is that Audible actually recognizes chapters of audiobooks (at least the ones purchased from Audible) and so it can jump to any of them. Your app couldn’t jump to a chapter because it does not even recognize the chapters. Your app also did not recognize chapters of an audiobook I purchased from iTunes and that one WAS in .m4b format, the format you just claimed worked well with your Bookmobile app.
You may have listened to hundreds of audiobooks and gotten a lot of ideas from people, but none of that matters if the app doesn’t do what people want it to (in this case recognize chapters). I don't have anything to do with any other audiobook app author and I'm not a cheapo who never buys apps. I buy apps all the time but I make sure they do what they claim. In a previous post you mentioned someone sounded angry at you. There's nothing wrong with trying to sell an audiobook app in the marketplace but to do so in a forum thread where people are complaining about a specific feature, promising that feature ... for a fee ... well, it's gonna raise some eyebrows when the product doesn't deliver.
