If you're reading this, you probably install a fair amount of apps on your phone or tablet. You may even install a custom ROM here and there. Android is a pretty amazing platform, all told, but it can also get grimy with leftover junk files, oversized caches, and other annoyances from all those installations.
Search through the Play Store for solutions to this problem and you'll find many developers eager to get your device running like new. Search Google for how much cleaning is necessary, or tips for cleaning and killing unnecessary tasks, and you're likely to get overwhelmed quickly. There's a lot of info out there.
The guys at KS Mobile may be the island in a sea of hogwash. They've developed an all-in-one solution that does everything you'd want a cleaner to do, and they do it beautifully.
Meet CleanMaster. The app's primary function is to clean out wasted space on your device's internal storage or SD card. Launch it and it'll scan the necessary files to do away with, and it'll do it in a snap.
The first option is the "standard" cleaner, which can clear out app caches and residual files. The standard cleaner alone cleared out over 700MB of unnecessary files from both of my devices.
The advanced cleaner goes even deeper, even scanning your music files for excessively large files. The advanced tab will cover app caches, "app leftovers," temporary files, and files larger than 10MB.
The app makes it easier than most to see precisely what's being done, and exclude any apps or files you're unsure of. This is pretty crucial to most users- no one wants to delete a critical file by accident.
Of course, that's just the tip of the iceberg. Besides the junk files category, the app also has options to boost Android's memory by killing unnecessary apps, a privacy option which can empty app histories and cookies, and even a built-in app manager.
All that may be enough to warrant the free download, but Clean Master isn't finished yet. The built-in app manager can backup existing apps or move them to your SD card to free up internal storage. It even monitors your system for newly installed apps. When you install an app, Clean Master will let you know if it can be moved to the SD card, taking you directly to the app's settings to move the app if you choose to do so. You can also add the widget for one-tap access to the task killer (handy for suddenly misbehaving apps), and schedule times to remind yourself to perform a cleaning.
All in all, Clean Master is about as complete, easy, and unobstrusive as it gets. It's a must-have for any Android owner.
