MEATER is the first truly wireless smart meat thermometer which can monitor your cooking using the free app available for iOS and Android smart phones and tablets. There are 2 temperature sensors. One can monitor internal meat temperature and the other external temperature simultaneously. Firstly, insert the MEATER into the meat. Afterwards, set up your cooking in the App, such as which kind of meat — steak, pork, poultry, fish, lamb or others, and exactly which part of the meat you want to cook. Then, cook and follow the App instructions. The app will estimate your cooking time and alert you when to remove from the heat, the amount of time your meat should rest and when your food is ready to eat.
