CCleaner is one of the most frequently used and popular maintenance apps that you can find in Windows. Now there is the official Piriform app for Android devices.
CCleaner for Android works as simply as its desktop sibling does: you just have to tap the ‘analyze’ button and in a matter of seconds the app will tell you how much memory you can free up and where you can free it up from.
In addition to these functions, CCleaner allows you to delete any app from its comfortable interface. And, last but not least, you can take a look at how your Android device is using its CPU, RAM, internal memory, and battery.
