Great work by SkaliStudio team. Would highly recommend this app
a) easy setup and customisation. Just follow the steps in documentation. Very few edits required to code -rest of content management is all through admin panel.
b) App UI looks great - exactly same like demo
c) Great customer support and quick turnaround for questions
If will be great if following can be considered for future updates:
a) List of bookmarks (favorite chapters) to be shown
b) Premium chapters be shown to regular users in locked state to help them get a sense of what is available in premium mode.
