Here is my explanation of the application design and function.
1. The application implements the functions of picture browsing, picture collection, picture clipping, picture adding filter, etc., and can share the application to friends. The purpose of the application design is to make the user's mobile phone more beautiful by replacing the wallpaper.
2. The application integrates the subscription function. The application allows the user to save three pictures for free. When the fourth picture is saved, the internal purchase interface pops up. When the user purchases, all the pictures can be saved.
3. The content of the app is updated once a week, each time updating 1000 images.
4. If the user has purchased the product, he can click on the restore to pull the bill. After verifying the bill, all functions can be unlocked.

Updating purchase price automatically in the App Store,3 days free then $0.99/week after payment.
