We all know there is no need of these types of applications in android devices. The main concept is that android device stores those data in memory which are regularly in use. These data are used by device to give a fast result to user.
This app clears the stored data and gives a message like memory cleared or 45% RAM cleared, etc. A general user thinks that the app is really working.
So, those who are reading my review, please don’t install these types of applications. These applications are only and only waste of data.
