is there a Droid castle link app ?

I was just wondering because the smartphones out there have alot of capabilities these days. They have apps for R/C cars for doing gearing calculations from Novak and another one or two if I remember correctly. I'd have to dig it up but they're out there. I'm sure someone is in a stall or with their face buried in a pc monitor plugging the code away in one manner or another that'll eventually lead to this or the furthering of the technology that gets it here.
