A few small issues and iOS limitations
Also, if you need to edit the Meta data on a generated M4B file you create, you have to add your full audiobook file and then add all new Meta data. There’s no way to just edit or make changes.
And, there’s no actual trial where you can generate an audiobook file and save it and test it before spending the purchase price. The purchase price is very modest, but I before purchasing.
The biggest problem is an Apple Books issue on iOS. Even though you can create the M4B file with Meta data on an iPhone from a collection of MP3 files (that actually works pretty well and only takes a couple minutes to put up to 19 or 20 MP3 files together) you cannot directly sync your new M4B file to the Apple Books app. You need to use a Apple computer to do the syncing process. So you might as well just convert the files on your Mac and then sync it to your iPhone after you’re done.
And finally, I wish there was some help documentation available.
