Clean Master is a comprehensive cleaner app for Android

"Comprehensive" since it's an all-in-one cleaning app: it allows to clear cache, unused files, app packages and history. Thus, Clean Master is way more than a simple task killer. It's KSMobile solution to keep your device at its highest performance.

There are fan and critics of task killers. However, most of the people would make use of an app for clearing cache and for detecting/deleting unused .apk located or residual files located on their devices. That's precisely what Cleaner Master allows users to do. In this regard, it's useful for everyone with device optimization concerns.

The importance of clearing cache. For example, when you're using browser, it saves the images as cache files. It's the same for other application and other processes. Clearing cache with powerful tools like Clean Master helps to speed up your device performance.

Likewise, Clean Master helps you to keep your phone protect against nosy people. Make use of "history eraser" to avoid other check out your Gmail, browser or Google Play history. There's no track after Clean Master.

However, there are two features that can be considered the strongest point of this app. First off, "Clean unused/residual files". When uninstalling, for example, big size games, extra data download remains on your device. Clean Master detects it and help you end up with free space gradual loss that happens to all Android devices.

Second feature that makes the difference is Clean Master's tool for deleting unused .apk. It uses to happen: you download the installation package of an app and then you keep it in your SDcard for months. Clean Master makes a list of .apk located on your device and allows you to delete them easily.

In addition, Clean Master is set in a user-friendly interface. A dashboard with four sections: "History", for clearing cache and privacy records, "Residual files", for deleting extra data downloaded (ends with the gradual loss of free space); "Tasks", its task-killer and, finally, "Temp APKs", that detects and allows you to clear unused APKs located in your device. What's more, if your device is rooted you will be able to enjoy an only-root feature: 1Tap Booster shortcut for a faster cleaning.

In brief, Clean Master is one of the most useful cleaning app due to its value added features, beyond task-killing. Highly recommendable.
