Clean Master (Boost & AppLock) is an excellent solution to clean and maintain your Android, an app that's easy, effective, and free.

Different types of cleaning

Clean Master offers different features to keep your device spotless:

Memory Boost: analyzes the apps that are running and lets you choose which ones to stop. This means you can free up RAM memory and speed up the performance of your device. In addition, it lets you create a widget to clean the device with just one tap.

Antivirus: analyzes the system for malware and vulnerabilities. The scanning is very fast and a final report shows the history of analysis. You'll also be able to access the Privacysub-menu, which lets you delete sensitive data such as browser history, call logs, SMS messages, and more.

App Manager: identifies the apps installed on your Android device and lets you remove those you're not using. It also includes a function to delete those temporary APK files that build up if you download outside Google Play.

Junk Files: Clean Master finds and removes temporary files, clears the system cache, and fixes basically whatever else is using up space on your device. The analysis also includes the identification of obsolete APKs and the Memory Boost described above.

Functional design

From the main screen, you can access a general overview of the status of the device and easily get access to the four main program areas: Junk Files, Memory Boost, Antivirus, and App Manager.

The Clean Master interface is easy to use and has a modern design.
