You want more faster apps?
You want to apply App Booster (Samsung Galaxy Labs) on other devices?
You don't know how to undo App Booster (Samsung Galaxy Labs)

Then you really need to use Volt.

Volt pre-compiles apps by using Android profile-data.
Pre-compiled data makes apps fast.

Volt acts in the same way as App Booster by Samsung (which is in Galaxy Labs now).
The difference is, Volt provides you undo function (clear profile-data and compiled data).
