For Android there's all kinda shit, iOS is harder.

You won't find (m)any public things for iOS, you can talk to @pvnk , but I don't know anything about whatever he does.

For android, there's DroidJack, AndroRAT, Dendroid, etc.

I've heard of AndroRAT before, but not the others. Thanks!

A remote administration tool is simply a tool that allows remote access. On iOS there are variants of not only remote administration tools, but spyware that can be hard installed into the phone's firmware. #themoreyouknow
