In the earlier stages of this project, I was working alongside as UI/UX Lead with 4 other of UI/UX designers. I mentored the entire process with team. We did surveys to gain insights on backgrounds, behaviour, and expectations of ebook readers, and we also did usability testing using the existing app.

Overview

Wun Zinn is a Ebook reading app where there are 700+ authors and 7,000 burmese books available for users around the world to buy and rent.

Project Goal

To find better ways to improve user experiences in discovering, searching, and reading books from Wun Zinn Digial application on Android. Improving these experiences may improve book sales and brand loyalty.

Problem

Even though Wun Zinn tries to keep updating their app with new books and features. Users usually stop using the app after few days. Not having a smooth user experience and having fixed reading screens has been their biggest user pain points followed by overwhelming Home Page with many book categories, unpleasant book reading experience and lastly, user had a hard time asking for troubleshooting via Messenger.

Design the process of Ebook reading as interactive as reading physical books, motivate users to spend time reading more books, help users discover interesting new books, and give better user experience in using Wun Zinn.
