Cengage Digital is an iPhone app developed by Cengage Learning Inc. It falls under the category of Education & Reference and is available for free. This app aims to enhance the learning experience for students by providing supplementary digital resources that come bundled with Cengage titles.

With Cengage Digital, students can access a variety of resources such as assessments, videos on difficult topics, and additional reading material. These resources are specifically designed to complement the content in Cengage textbooks, offering students a more comprehensive and interactive learning experience.

It's important to note that the free digital content in Cengage Digital can only be redeemed by scanning the "License QR Code" found in the purchased copy of the Cengage textbook. The QR code has a redeem/activate validity period and the period of access to the digital content has an expiry date.

Please be aware that Cengage Digital is a separate app from Cengage App, also launched by Cengage India. Cengage Digital focuses on delivering digital supplements for 2021 editions and beyond, while Cengage App holds digital supplements for books up to the 2020 edition. The appropriate app to download is clearly indicated on the printed book.
