As you've used the iTunes Store, App Store, and iBookstore, you've probably noticed ratings and reviews from us and other customers. You can sort customer reviews by most favorable, most critical, most helpful, or most recent. You can also indicate which reviews you found particularly helpful. Join the conversation by posting reviews and ratings of your own--just click or tap the Ratings and Reviews tab (which is just called Ratings on iPhone and iPod touch), then click or tap the Write a Review button at the top of the Customer Reviews section. You can rate the item, write a review, or both as you choose.
