“Great little app, my phone is nearly new but battery wasn't lasting a day and it was getting slower…”
  • Great little app, my phone is nearly new but battery wasn't lasting a day and it was getting slower. After using this for a few weeks now it definitely seems to have improved both speed and battery life. Only thing I hate is that it constantly gives me warnings that my device is performing poorly! !

  • Had a similar app (different company, DU) previously which was actually slowing down my phone (galaxy s4) & sapping my battery at an alarming rate, so this app is really refreshing & actually works! Phone is operating smoother, faster & the battery lasts all day, big thumbs up.

  • Great. Does so much to clean up junk and free space as well as reduce CPU AND RAM usage. Even kills apps that cause the phone to over heat in the background. Idle app manager and a great widget to clean your memory for battery saving.

  • I use to have this app but it told me to uninstall some apps and I uninstalled this app so when I uninstalled a game it left some trash that could have killed my phone this app is a phone (to me a life saver ) saver.

  • My phone was eating battery power like crazy! After installing this, and stopping google now, it showed me that Facebook is also killing the cpu! So glad I got this. It is very efficient and easy to use. For the Samsung galaxy s4

  • I recommend this app to all my friends and family who are ALWAYS on the go and need to free up space on their phones! This is a great app that also cools your phone and makes you aware of what app secretly starts your phone to access data!!! Great job to the developers!!!

  • The Clean Master app is amazing. Its very easy to use, and very quickly cleans up junk. I freed up 6 GB of space the first time I used it. If an app is constantly restarting it will tell you and offer the option to force stop the app. Works great. Try it!

  • One of my top favorite apps!! A simple, yet reliable task manager, the Clean Master app is a necessity when it comes to keeping your phone running fast. The Clean Master app also helps by recommending daily system scans, antivirus checks, and even letting you know when your battery is over working itself.
