  • This app let me save a lot of space in my phone. Also, it gave me a time to back up pictures so it would be ready whenever I deleted it accidentally. I recommend this app for you. Great job for those who created this.

  • I love this app , Dont even think about if it works because it does and its awesome. The downfall for me is the notification for deleting duplicate pictures. I take too many of the same pictures for that.

  • Its a good app almost perfect but it consumes almost 40mb of ram with 2processes and services. Still its an essential app for devices with less than 512mb ram as it manages other background apps and saves free spaces for efficient working.

  • Finally a way to take control of my phone and clean out the crud. Longer battery life and phone running faster. Couple this with battery doctor and root your phone for total control. Puts life back into older phones.

  • This app seems to be great at telling me installed software that is restarting and consuming memory as well as the phone's CPU.. I do get annoyed when I get notified while not using my phone, as one would think my phone would drain energy more and warrant a msg while using it.

  • I was skeptical about downloading to my Note3 but after using it my phone is working faster and battery life is extended. Be careful and read though so you won't erase pictures and things you wanna keep!

  • I love clean master, I've used it for what seems like forever across multiple devices and it has and does always work for me! I love the CPU cool down feature the best. I just wish the ram cleaning widget was adjustable.

  • This is Not for everybody. You could lose pics and files your not even aware of. So if your NOT SURE what it is, or what it does, Don't clean (Delete) it. Once cleaned, it's gone forever. So be careful. Make sure of what you're doing! This is a very useful app. Easy to use. I use it everyday.♡ Tina

  • I am always doubtful of programs that promise the moon, but I'm happy to report Clean Master delivered the moon, Sun, and the Milky way. Runs in the background, efficient clean, and my phone runs much cooler and faster. Clean Master is a must have app.
