I've been running the newest app iDevices (app button shown in the lower right hand corer of the pic) with my original iGrill now for about a month. I really like it and the therm has performed flawlessly. The transmitter seems to not be going through batteries like it used to. The range is a bit more, but that's never been a problem for me. I hope this means the the new iGrill2 is going to worth buying when its released.
