Yet to experience fully

I’ve only downloaded one book so far, and this was to my iPad. Seems a really good site but I rarely read books on anything but my Kindle, and I don’t think this app will work with that. Therefore, for me personally, I will get limited use, but that is no fault of the site, the site is good

Prolific Works App

I have just downloaded this App and have a little experience of using it. First I was a little perturbed that I had ‘another’ reader on my iPad, but trying to use the App, for this review, I could either send the book to my Kindle App, or use Kindle to open the book (plus.. I didn’t check further!) so in effect it is just a list of books that I have selected and they have to be sent/opened in my Kindle App. I did think that I would not like yet another reader, but I think I now have two lists of books: one list on my Kindle App and another that is opened by my Kindle App! I will keep this App as I want access to the books but I am not impressed.

Good with reservations

This is a really good application it enables you to check on your free unread catalogue and here is the reservation you cannot open and read these books in this application you must transfer to another reader app so if you wish to remember where you purchased these books you first save to app then transfer to read two words Data Storage.
