Your talking about the same app no ? Smart status bar ? ( when in full screen mode )
Im using this app to hide the notification bar after 3sec time out and POP down when i get a notification.. . . i don't know what your doing with it if this is not what the app does !
Im mental or you need some coffee ?
What I was trying to say is it doesn't by itself hide the status bar for u since u already stated it shows up in apps if I understand u have it hidden from launcher but not apps I use cm expand desktop which keeps it hidden 24/7 except on Lockscreen ( status bar cannot be hidden on default Lockscreen unless u decompile ur Lockscreen from ur ROM ) as far as hiding it on the Lockscreen the only was is to use 3rd party apps like widgetlocker or hololocker
