Need a Moble app scrapper

Hello Guys,

We need help in scrapping images and contents from APK.
Contents have already been uploaded as a story, so every story will have many chapters

If you can just download the first two chapters, then we will give you the account login, So that you can make a script that will help us to download all the stories' content.
The contents mostly are images
So when the script will download the images, need to store them like

**Folder Name(will use story name)
**[ chapter-1_1.jpg , chapter-1_2.jpg for chapter 1
** chapter-2_2.jpg , chapter-2_2.jpg for chapter 2 ]

Thank You
