So just got a notification that I am close to my limit. I have 5 GB. Well I went into there to look and I have apps in there that use like 21MB. What exactly does the icloud have to do with apps. I have a PC so probalby have no clue what I'm talking about. But does icloud like store your app data and it takes up alot of space? What would be my best say to arrange it better?
