I own an App in Google Play:
[login to view URL]
I want it to be upgraded with new content and with new logic
I have 1500 articles, each article has to be displayed one by one
only one article should be shown every day
user can read previous articles by selecting previous days
I do not have the source code for this App
its simple, 2 Activity app
Same App should work in website as well, you can use Angular or React JS for this
