Users measure blood sugar by attaching a continuous blood glucose sensor to their arm for 14 days instead of a finger blood sampler. You can receive blood sugar data for 14 days as a csv file, and based on the blood sugar data measured for 14 days, it generates blood sugar synthesis data through GAN (Generative Adversarial Networks), an artificial intelligence technology. It provides exercise management and diet management services by allowing users to record exercise and meals through the app.The MetaAB app consists of four main functions.The first is a function to register as a member and enter member information. This is a member-specific personal information management function through membership registration.The second is the blood glucose data input and monitoring function. It is possible to retrieve blood sugar information through NFC and monitor the users blood sugar in real time through a graph.The third is input and monitoring of food intake and exercise information. It is possible to take and save pictures of food intake and exercise, calculate calories intake through the amount of carbohydrate in intake food, and predict blood sugar rise through the amount of food intake. In addition, it is possible to calculate the calories burned through the exercise event and time, and it is possible to predict the blood sugar drop through the exercise event and time. Finally, it is possible to monitor food intake and exercise information through the calendar.
