This research project investigates how to design apps on smartphones based on user-centred design theory to improve the experiences of seniors. Based on my grandfather's terrible experience with WeChat, a Chinese social network, I investigated and explored through my own practice how WeChat can be simplified and redesigned to support people like my grandfather.

This project takes on a user-centred approach, considering intimately the various challenges that seniors encounter when using smartphones and considering how to solve them. As a communication designer, the research has given consideration to the user's vision, thoughts and health status to design a new version of WeChat targeted at seniors (lite mode WeChat).
