The "SUPPORT+" project, initiated by the Department of Clinical Oncology at the University of Hong Kong, aims to support cancer patients, caregivers, and the general public through the mobile app "SUPPORT+." We have successfully engaged with over 50,000 users across five online platforms, including iOS and Android apps, Facebook, Instagram, and YouTube, resulting in more than 333,000 user interactions. To further promote our app within the local community, "SUPPORT+" has organized public events like talks, booths, and workshops. Collaboration with various organizations, including District Health Centers, social service groups, and NGOs, has expanded our reach and impact.
