APP designToday, we started to make the app in order to help our product become more convenient. Today’s process consists of two major parts. First of all, we made a log in or register system for our users for the sake of restoring their important information. Therefore, users could access to their own condition on different devices whenever they want. and we also design a register and login system,it provide a opportunity for consumer experiencing a better service that provide for individual. Moreover, we conceived an ideal appearance of different parts such as home, Bluetooth and device choosing this kind of stuffs. It’s quite complex, after all, because we not only have to create the objects and images to represent different modules but also have to establish the logic operation behind it to achieve a series of commands. In the next movement, we planned to create a data base to store a large amount of data about these and build a line chart to represent some real-time data clearly.
