A large number of Kindle books purchased from Amazon are in AZW3 format. Most of them are protected by DRM. But DRM free books in AZW3 format can be copied, shared and viewed just like Mobi and other unlocked ebooks. For example, you can download Kindle for Android, Windows or Mac and use them to read DRM free books in AZW3 format on your smartphone and computers. Unfortunately Kindle for iOS is not an option. We’ve tested Kindle app for iOS on an iPhone and found that AZW3 files, even DRM free, cannot be read with the Kindle app. Is there any way to read AZW3 books on an iOS device?
