CityHack 2019 - Ching Ho Ball


HappyJai is an iOS application with the following features:

  • A forum for academic and school-life related discussion
  • Disguised as an easy-to-use IM application.
  • A sentiment analysis powered by AI that understands your sent messages.
  • A page that tell you your emotions through simple design.


In order to address the potential depression/mental problem for university students, HappyJai is a mobile application designed for students to visualize their level of everyday happiness, and to let them realize whether are they in a healthy mental state. We provide a forum, with chatrooms and direct messaging for students to communicate with their schoolmates and the AI in HappyJai will analyze communication data of every user and calculate their rate of happiness.
