Power Cleaner for Android
Features
► Junk Clean & Memory Booster
Frees up storage space and optimizes device performance by removing redundant background tasks.
Stop apps that start automatically to reduce initial boot time and reduce memory usage
► AppLock
Protect your privacy by preventing others from accessing your personal, private, or sensitive apps, such as Facebook, Instagram, SMS App, photo gallery, etc.
No idea why these apps are so popular but this is more of the same. Android itself manages memory and does not need an app to.
It works like a charm.
