一、Layout
Advertising, resource sharing and the IAP
1. free version into the interface will automatically refresh to display full-screen ads, there is a corresponding "IAP" remove this feature. Although full-screen advertising is part of my income, but there are people interested in one hand, so I offer convenient buttons you want to see some of the full-screen ads.

3."IAP" section mainly "No Ads", "do not automatically display full-screen ads," "all sound package download" and "All the pictures automatically download". "IAP" advertising section and resource access "IAP" provides preferential payment If you need all of or related content, you can save some of your payments.

The main computing functions
Support equipment rotation, the vertical direction is conventional computing; horizontal direction is the scientific extensions;
In the main computing interface, if paid
"No ads" IAP, the original ad position display background image thumbnails, allowing you to switch favorite style interface.

Setting Functions
Skin Style Configuration:
Navigate to the color scheme View, can be configured with the skin color of the button text style configuration; APP provides 65 pictures background.
