This smartwatch is designed to solve the problem of children being left behind in the car. The watch
is connected to the seat in the car via Bluetooth. When the adult leaves the car for a certain period of
time, the watch vibrates violently. At the same time, you can send voice to the children in the car by
clicking on the watch display to play a comforting role.
