The iGrill comes with a probe for you to put inside your grill. The probe is connected to a Bluetooth display, which communicates with your Apple devices via an app and lets you keep track of the temperature in real time.
iDevices says that the iGrill supports long-range Bluetooth, with distances up to 200 feet. This allows you to do other fun things, such as play a video game, while cooking, and you still won't burn the meat (or vegetables).
According to iDevice, the iGrill is designed to track temperatures of up to 400 degrees. As things tend to get a little complicated after a few beers, make sure you remember to put just the probe inside the grill, not the display component, which is supposed to be left outside the grill.
If you can't wait to see the demo and want to try it out for yourself, the iGrill is available now for $100.
