degrees Celsius: App's startup page design has always had two distinct views: need or not. The reason for this is that the app starts with a little time initialization process, developers can use this initialization process time to show some of the brand information, and the reason is that as the device hardware performance, the app can be started faster, remove the startup page to reduce the app, It also allows developers to pursue app performance more.
Of course, the app that really can do seconds is too scarce, so the launch page is still a means of "deceiving" the user's startup time.
