I had installed this app because my phone started hanging and there were viruses in my phone.but after using I would share my experience.
First and major problem was after installing this app, when I used to install other apps it didnt show up anywhere.niether homescreen nor in app section.but when I open playstore and open that app, it shows it is already installed.irritated a lot.
Secondly my mob started hanging a bit after installing this.this app has built a data more than 150 mb in my internal storage.
The layout is normal.app is userfriendly too.
But the major bad features of this app I had already mentioned above because of which I uninstalled this app.
