 These can be applied through theming "platforms" such as WinterBoard(iOS 2 – iOS 9), Anemone(iOS 7 – iOS 11), the more recently SnowBoard(iOS 11 – iOS 13) and iThemer (iOS 11 – iOS 12).All of these theming "engines" can be installed via third-party Package Managers on Jailbroken devices such as Cydia, Sileo, Zebra, and Installer.app.Applications and user interface elements of SpringBoard can be manually themed but most users choose to use these theming platforms as they are more stable, straightforward, and offer features such as the ability to easily enable/disable themes seamlessly whenever the user chooses.
