Slices cydia tweak allows you to create many different setting and data bundles for any user application. The process is as simple as tapping and naming a slice. These slices can easily be switched between, and all data is completely separate each slice.
For example, if you don’t want your high score on a game to be overwritten with someone else’s score using your device, you can quickly create them a slice for that game and the scores will be specific to that slice. Another example is if you have many accounts on a social network. Usually, you would sign in and out to change accounts. With slices, you can reduce it to 2 taps to change to any one of your accounts (no login needed).
Specific slices can also be easily renamed, deleted, and created in the Settings application. Preferences such as whether or not to ask which slice to change to when launching the application or which slice is the default slice can also be configured through the Settings application.
