  • My Galaxy S4 was slow to load, slow to react to my typing and my battery was draining quickly. Now I have the ability to shut down additional processes on my phone in order to save battery life.

  • I've been using the app for quite a while and it does help optimize memory usage and free storage space, not to mention that it will tell you when an app is using too much cpu and helps you get it fixed

  • My phone frequently over heated (yikes). I think I would just clog up the memory too much and too many background processes were running all the time. This app keeps it quick and easy to clean out your phone. Now it runs quicker and isn't over heating anymore!

  • My Samsung Galaxy is 18 months old. Recently the battery has begun to die very quickly. It wasn't a gradual decline either, more like one day to the next. This lovely little app helps tremendously and also keeps it from heating up in my pocket which is not only bad for the battery but also creeps me out.

  • Pretty impressed. Phone really is running faster and having less issues and lag. Also noticed it's not overheating lately. My battery seems to be lasting longer as well so I'm happy all the way around.

  • I have been using this for awhile now, I used many so called cleaners. But this one takes the cake with its smooth interface, very simple layout, and easy transitions to let you know everything about your phone

  • Clean Master keeps my Galaxy 4 running in tip top shape. Reminding me to clean out junk files, tells me which apps are slowing me down and even when my phone is over heating and closes out those apps. Love this app everyone should use it.
