CookProble APP is a wireless Bluetooth meat thermometer platform that can be connected with multiple Bluetooth meat thermometers at the same time. It collects the internal and external temperatures of food through the Bluetooth meat thermometer, and then transmits them to the APP. You can choose on the APP and select the required doneness for the recipe and preset the target temperature. When the internal temperature of the food reaches the target temperature, the user will be notified on the APP and the battery box.
