iBooks

iBooks is a former name of Apple's digital reading platform for ebooks and PDFs. It was released in 2010 as an iPad application, with the iBooks Store serving as the storefront for purchasing and downloading titles. Content acquired through the store used Apple's FairPlay digital rights management and could be read offline on supported devices.

Users could organize their library, create collections, and access features such as bookmarks, highlights, notes, and a built-in dictionary. The reading experience offered adjustable typography (font and size), background themes, and layout options, along with search, table of contents, and progress tracking that syncs across devices via iCloud when signed into the same Apple ID.

In 2018, Apple rebranded iBooks as Apple Books and updated the app's design and storefront. Apple Books remains the primary method to read, purchase, and download ebooks on iPhone, iPad, and Mac, with the service tightly integrated into the broader Apple ecosystem.

Apple Books competes with other ebook ecosystems such as Kindle and Google Play Books. While it benefits from seamless Apple integration and a broad catalog, it is primarily tied to Apple devices and the availability of titles may vary by region due to publisher restrictions.
