Merchanting Apps?

Are there any good merchanting programs, or apps out there to better monitor the GE? I'd imagine by now there has to be a few. Just trying to get back into the swing of things.

The only one to speak of is the official Runescape Companion App which will allow you to directly access the Runescape Ge from mobile devices, provided you're using the Runescape Authenticator on your account(s).

I'll check it out, thanks Phileep
