The device measures the temperature inside the pot and sends the data to a smartphone. In the oven the plug probe sensor measures the core and the ambient temperature.
If the temperature is not within the range, an alert appears. This can protect your food from burning.
Also the device has an over boil detection and sends an alert to the smartphone as soon as foam rises to the border of the pot.
Cooky has a memory, it records the temperature independently without the smartphone
Cooky turns on automatically if the temperature in the pot increases. It records the temperature whether the App has been started or not.
As a result, no data is lost and the times of the cooking steps remain correct even though you may have started the App later.
