I am giving this review for those who are using less ram phones i.e less than 1gb. Greenify is the app which you can use to install more apps in less ram phone.All you need to do is root your phone greenify doesn’t do anything yet it temporarily turn off the particular app Which you don’t want to use, but is till running behindin settings menu and using your precious ram. which is running behind. you can not do this without rooting your phone . so be assured to Root your phone first.
You will get very smoother performance by installing this app . This App is totally free. So feel free to install and use it. This app also have paid donation version for additional features like turning off the system apps. But I suggest you to not to interfere with the system apps which can cause harm to you smartphone.:)
