Modern life is very rich, but obesity has brought a lot of trouble to people. So we designed a APP for weight loss. First, according to the requirements of APP. Users must create body information, including size and weight. You also need to configure your target body weight. Users also need to work with the scale, and if you lose weight successfully, you need to update the data manually in the APP. On the homepage, we use different colors to distinguish, making it easier for you to observe weight data. On the date page, you can also see your weight loss record. However, please note that this is an auxiliary procedure, and everything depends on the user's own efforts. Applications can help weight loss users. Application does not guarantee that all users can lose weight successfully.
