It enables users to install apps that are not available on the official App Store, such as modified or tweaked versions of existing apps, emulators, and other unofficial apps. Scarlet simplifies the process of app installation by handling necessary certificates, providing a user-friendly interface, and offering additional customization options for an enhanced iOS experience.
