The best app for this would probably be Tapatalk, as I'm sure this wouldn't be developed any time soon. As far as I'm aware the Toribash community isn't exactly stocked on developers, so if the suggestion isn't game-changing it likely won't be implemented.

If you're running an iOS device, you can add http://forum.toribash.com/ to your home screen; the website is just a click away then. (:
