Just in time for the new iPad’s launch tomorrow, Amazon has updated its Kindle app to take advantage of the Retina display.

Both the iPad and iPhone version have received the version 3.0 update. One of the other new features is a streamlined viewing structure with cloud and device tabs. All items available in your Kindle library can been seen in the cloud tab, while items already downloaded locally are seen in your device tab.

In the cloud view, items can be downloaded locally with one tap and can be removed at any time to free up space on your device.

With both the iPad and iPhone version, users can also view their content in a new grid view. Items can be sorted by title, author or recent.

Beyond the new options, the reading experience remains the same with options to search, bookmark, sync with other Kindle devices and view text with three color schemes and six font sizes.

And while there has been some concern that Retina-enabled apps on the iPad might be substantially larger, that doesn’t seem to be the case with the Kindle app, which only went from 17.5MB to 19.2MB. That should be very good news for owners of the new 16GB iPad, including me.

Have you downloaded the new update? Tell us what you think. I’m glad to see Amazon made sure to give readers the full Retina experience on launch day.

The Kindle app is available on the App Store for free.
