It is totally unnecessary app and you should not install on your phone. I would recommend not to use this kind of 3rd party apps .it is useless . You will always see they are adding new kinds of features in it. Which are not helpful. After cleaning it works for few minute again the same problem started. It is not actual working just showing fake result it does not clean any apps. This app is just waste of your time, net, and phone.
