Need a free app to remotely control my desktop

Hey, people!

Does anyone know a free app (BB10 or Android) to remotely control my desktop via my home wi-fi network?

Thanks!

I think Teamviewer works (Android). I tried accessing my office laptop using it. Also does not require Admin rights or installed in the PC which makes it handy.

Why must it be free?
