Friends, I have very bad experience with this app. This app is totally fake. It kills the background running apps which takes more battery when we restarts those killed apps again. System stores those data in cache memory which are regularly in use to gives fast service to users and this app cleans cache memory.
I think it is very difficult to find an application that actually saves battery. I dont know about other apps but this app is totally fake and from my personal experience I dont suggest you to download this app.
Thanks.
