Wellness is an important indicator of quality of life. It is a holistic idea that includes all positive aspects of lifestyle, not merely referring to the state of the absence of diseases. In this connection, improving wellness can lead to enhancements in the quality of life. Thus, encouraging the public to improve their wellness is crucial to making a better world. The same idea is also outlined under the United Nation’s third sustainable development goal: Good Health and Well-being which aims at ensuring healthy lives and promoting well-being for all at all ages.

To address wellness as an important issue, Hong Kong Education City (HKEdCity) and HKUST-Lee Kum Kee Happy Family Learning Center are jointly organising the ‘Code2App 2020: Wellness Power-up' challenge for primary and secondary school students. Students can make use of their coding and computational thinking skills, along with their creativity to build Android apps, to arouse the public awareness of improving wellness which includes maintaining physical health, improving mental health such as stress management, attaining happiness in life, and achieving interpersonal harmony.



** 'Code2App 2020: Wellness Power-up - Application Development Contest' has come to an end, click here to review the competition result.


A. Objectives

  1. To empower teachers and students to utilize computational thinking to code using App Inventor
  2. To stimulate students’ creativity and apply computational thinking through the development of an Android app in the related theme 
  3. To enhance students’ awareness of wellness
  4. To promote harmonious family relationships by collaboratively solving a problem


B. Learning Journey

The scheme is a learning journey consists of three major components: ‘Learning’, ‘Contest’ and ‘Extension’.

Part 1 – Learning

  • An online course on App Inventor and workshops are offered for participants to learn coding and computational thinking.
  • Online Course: The course includes training on computational thinking and how to use MIT App Inventor, where participants can get to know the design principles behind application coding. Teachers are also welcomed to register and make use of online course materials for school lessons.

  • Workshops: Teachers and students can participate workshops with hands-on experience in developing interesting Android applications.


Part 2 – Contest

  • Participants can choose to enter the Application Development Contest of next stage, which they will create an Android app about improving wellness with the knowledge learnt in the course and workshops.
  • There is no limit on the number of participating teams for each school, and each team should consist of 3 students.
  • Students will apply their App inventor skills to build Android apps that can promote the awareness of improving wellness.


Part 3 – Extension

  • Shortlisted finalists will present their ideas and works in front of the judging panel on 9 May (Saturday).
  • The Family Inclusive Award will be given to the finalist who can best demonstrate the involvement of family members during the process of making or using the app OR the impact of promoting family relationships through the use of the app.
  • Besides competing for the champions, finalists can also join the free STEM courses and activities in HKUST during summer holiday, so that they can further their journey to become a coding expert.

  3. Each team needs to submit for the first submission:
    1. Introductory Video (3 minutes maximum, demonstrating how the app arouses the public awareness of wellness)
    2. Introductory PowerPoint file (within 10 slides, including the ideas of the submission, the problem to be solved, the technical aspect of the app, etc)
    3. App Inventor project file (aia file, 10MB maximum file size) and the Application package file (apk file)
    4. The use of communication between App Inventor and IoT devices is allowed.
  4. Finalists will be shortlisted, and the team members will give a 5-minute presentation which will be followed by a 5-minute question-and-answer session in front of the judging panel on Grand Final.
  5. Each team can only submit one entry.
  6. Entries of the finalists will be additionally assessed to compete for the Family Inclusive Award. The criteria are based on:
    1. the degree of family involvement during the process of making or using the submitted App; or
    2. the impact of promoting family relationships through the use of the submitted App.
  7. All entries must be original and not be published on other occasions before. By submitting an entry, the participant affirms that the entry neither contains any third party copyrighted materials nor infringes any intellectual property rights of any third parties.
  8. Submission of any entry indicates that the participant has read and accepted the Rules & Regulations of the competition.
  9. The Organisers reserve the right to exhibit the participants’ ideas/Apps. 
  10. Copyrights of the ideas/apps are retained by the participants themselves.
  11. The Organisers reserve the right to amend, extend and interpret the competition guideline and rules without prior notice.
  12. A certificate will be issued to students who have completed the student training workshops.
  13. In case of any dispute, the Organisers reserve the right of final decision.



  • Each division: champion, 1st runner-up, 2nd runner-up and the Family Inclusive Award winner will receive amazing prizes.
  • The finalists can take a free credit-bearing course and/or join a free STEM workshop in HKUST during the summer holiday.
