The Kindle for iOS app has a new update rolling into the App Store today that brings several enhancements for readers. The new build is version 6.6 for those keeping score at home and should be available for everyone at this point. The big news in this update is the support for Kindle Unlimited subscriptions and Prime Reading right within the app itself.
Kindle Unlimited is a $9.99 per month subscription that allows you to read an unlimited number of books at no additional cost. Think of it as a pay-for library where you can borrow a book and read it. Until now, you had to go to the Kindle Unlimited site to borrow the book and then it would be added to your Kindle for iOS app on your devices. Now, if you have the subscription, you can add books to your Kindle app from within it, saving you time and steps.
