Why it's similar
Apple Books is a full bookstore and reader for ebooks and audiobooks with no subscription, synced progress, reading goals, and curated recommendations across Apple devices, closely matching Kindle's complete reading service. Both offer millions of titles and bestseller charts.
How it differs
Apple Books runs on Apple's store rather than Amazon's, so it works only on Apple devices and ties purchases to your Apple account. At 4.43 stars across about 79,000 ratings, it rates below Kindle. It is Kindle's main non-Amazon rival, not a companion.
