I've pined tons of iPad apps, but this is the first kindle app list I have come across! I found this great collection of the 12 best free kindle apps for kids on HeidiSongs page. Great way to incorporate digital literacy!
Install the FREE Kindle App on your device. From this website you can choose the appropriate age of reader. You can look at the star rating that readers have given the selection and also see how many ratings that book has received. If you find a title that you would like to add to your device, click on the title. You will be taken to the Amazon page where you can "purchase" the free book. This will send the book automatically to your Kindle bookshelf.

I use the Kindle app on my iPad and it works wonderfully.
