Cellular Data

There are some redesigned opinions about Cellular Data app below:

1.Use the background color of the sky to represent the residual ratio;
2.The floating speed of the cloud is calculated automatically according to the date flow condition;
3.Home screen shows residual flow of the month and last 7 days usage which are the users most concerned about;
4.Notification Center displays today's usage, real-time flow rate and residual flow of the month;

I just want to optimize previous designed style, please leave a message to me if you have a better suggestion,thank you!
