If I’m reading a book from Amazon with this app, it works perfectly and keeps me on the same page when I next open my Kindle or Kindle app. My reading experience is great.
Deleting couldn’t be more difficult (it’s not a hassle to delete one, but when you’re cleaning up).
Here’s the problems:
My iOS Kindle apps (iPad and iPhone) sync everything between them: open it up on the Kindle or iPad app or iPhone app and they’re all on the same page; this works for books from Kindle AND Documents (books from other sources ARE CONSIDERED DOCUMENTS) buy not on the Mac.
The Mac version won’t sync documents so it’s not as useful to me, I buy my books from various locations (these get labeled as documents). This makes no sense to me: The Amazon Fire is a competitor to the iPad and the app supports all functionality (pretty much giving no reason to get a Fire, but most people still buy from Amazon with the app) but the Mac (which Amazon doesn’t make a competing product) doesn’t have enough functionality, don’t they want me to have the word “Kindle" in my head (and not iBooks?).
If you want to delete more than one book at a time, good luck, they make it as painfull as possible.
I know my complaints are very technical, but I hope I explained why I rated it low. There are a lot more low reviews here that I can’t fingure out what they mean...
