Thanks for that Der Kommandant.In my opinion you don't need cleaning apps like the one you mentioned and you shouldn't pay for it. If you still want one I would recommend you to use Onyx, it's trusted and free.
You don't need "cleaner" or "maintenance" apps to keep your Mac running well, and some of these apps can do more harm than good. Most only remove files/folders or unused languages or architectures, which does nothing more than free up some drive space, with the risk of deleting something important in the process.Mavericks Cache Cleaner....Anyone heard of it ?

You can check the following locations for apps that automatically launch on startup and delete any you don't need/want:
How do I do that ?
