Cache clearing app

Hello can someonw recommend me an app that clears cache after I have uninstalled an app. Anyway I just want some space on phone and I dont know will that kind of apps slow my meizu down? Any suggestion,tips?
Thanks :)

Doesn’t the built in function work?

It does but lets say that I have 10gb of storage, I install app that is 2gb large I should now have 8gb of storage left. But after I uninstall that app or game my storage wont go back at its first position it is going to be 9gb 800mb or something like that? Do you get me?
