Function Settings：
Calculate the weight of the baby through the difference between the two weight data, and set the corresponding data for the baby. The steps are as follows:
1. Adults weigh first -- when the weight is stable, then hold the baby and weigh -- the baby's weight will be calculated automatically after completion.
2. Set baby information.
Note:
Currently, only the latest Version of Android has this function, and the iOS version is not supported for the time being. It is recommended to follow the APP update later.
