iDevices is behind some interesting smart thermometers. The iDevices Connected app already allowed users to monitor their food temperature remotely from a smartphone with iGrill and Kitchen Thermometer products. Now you can use your Apple Watch to monitor real-time temperatures, set temperature goals, and see details of temperature progression as you cook your food. The app will alert you when your food is cooked.
The iGrill2 and iGrill Mini set you back under $100 and $40 respectively.
