Clean Master Cleaner is an app that helps maintain your Android device and keep it running well.

Android devices can be prone to poor performance over time because of installation and saved data bloat, unoptimized caches, large histories and so forth. Clean Master Cleaner exists to help you keep those problems in check without having to a factory reset and resync every few months.

The program is free to use and includes a number of different optimization mechanisms. It can help you end and disable tasks as well as manage programs that launch at start up. It can search for files that may be no longer used or are unnecessarily large. It can help identify installed apps you no longer use and then uninstall them. It also cleans caches and temp files. Sure, they’ll return, but this keeps them in check since many programs don’t optimize that space.

Clean Master Cleaner can help with your personal data as well. Clean your browsing, call and other histories on demand. When you uninstall an app, it will go behind that uninstall process and get rid of all residual files. Residual files are a big reason for storage usage creep. It features a lightweight AV solution that can detect and eliminate malware. It also has a boost feature, which optimizes many of the settings on your phone or tablet with just one click.

The app lacks recovery options. It doesn’t do anything without your permission, but if you give it the go-ahead and then change your mind, you may be out of luck. Therefore, it’s important to be careful when using this program and never delete anything unless you’re sure you don’t need it.

Pros

  • Cleans files, caches, histories and more
  • Uninstalls apps and residual files
  • Antivirus protection

Cons

  • Few recovery options

A few minor updates to make Clean Master an even better Cleaner & Booster, with enhanced Antivirus protection
