Food thermometers are critical for making sure you cook your food just the right amount, and the Kitchen Thermometer by iDevices makes that easier for you by connecting straight to your smartphone via bluetooth to let you know the internal temperature of whatever you place it in. It also comes with support for multiple thermometers, so if you're cooking a turkey or a leg of lamb, where different parts of the meat cook at different rates, you can make sure everything is going smoothly before it becomes an issue. It comes with presets for nearly every different kind of meat and preferred doneness, so you can get it right without having to double check. The Kitchen Thermometer comes in two variants, one with a touch interface, display, and two temperature probes, and one smaller one with a single probe. They cost $79.99 and $39.99 respectively.
