This app does what it should, and the more than thoroughly! The app adjusted your smartphone or tablet in an instant, removes any debris and garbage, the first passage was removed on my Sony Xperia over 500 MB (!!!) garbage, has angesammlt within just 6 months. On my Kindle Fire HD, there were "only" about 300 MB to 1 (!!!) month-to-use!
The app does almost everything by itself, even for absolute beginners!
So I can only recommend to anyone, the app is a must for every Android smartphone and tablet owners !!!
