Greenify is a free smartphone app which helps to extend your battery life, improve memory and speed up performance. It does this by reducing what your apps are doing behind the scenes, such as sending push notification or transferring data. This can also help reduce the amount of online data used. Greenify tracks which apps are most active, allowing you to decide which are important.

Cutting Back

With a simple installation and a handy resource manager, Greenify is one of the more user friendly resource reduction apps. The interface is clean and simple, if a little bland, and the separate functions are clearly explained. If you just want to improve the speed or memory of your phone, the app's functions ends at this point. Hover, it also features a number of additional features like root settings and GCM notifications which are great for the more technically-minded user.

Set and Forget

Resource managements apps are a useful tool to improve the performance of your phone, and Greenify shines with its ease of use. It is a well-designed app, available for free and runs without fuss but does have its problems. One of the worse is its own memory use and data sending. If not switched off, the app will send data about your phone back to the makers, so be sure to change it under settings.
