Looking for custom key map app

I am looking for an iOS app that would allow for me to connect to my co outer through wifi and turn it into a custom controller and allow me to make as many or as few buttons with there own icons that I would like.

If anyone knows of an app like that let me know, thanks.

Do you mean router - and are you asking for a remote type app? And custom control what?

I found this - to control my computer through my iPhone.
