Apple Gift Cards can be redeemed for a wide range of Apple products and services, including apps, music, and books. Redeeming an Apple Gift Card Code Free $100 is easy using the native apps on iOS and iPadOS, and can also be done on a Mac through the App Store or on an Android device. While Apple used to offer several different types of gift cards, the company has largely moved to a single Apple Gift Card. This approach is great for consumers because these cards can be redeemed for anything from apps to physical products.
