Change it in my profile. Fan Ju is an app that can help us control our diet and lose weight scientifically. When we open it for the first time, we will set our current weight and target weight. Then Fan Ju will tailor a diet plan for us, record our daily weight and diet, and accurately calculate the calories contained in each meal. After updating Fan Ju, we have added the function of modifying and deleting existing records, which can modify the target in my data, improve the menu function, optimize the experience of using the menu, and add more basic functions.
