Personalised Real-Time Air Quality Information System for Exposure – Hong Kong (PRAISE-HK)

PRAISE-HK is an innovative mobile app providing real-time, geo-localised air quality information anytime, anywhere on your devices. The app helps users to evaluate air pollution exposure and provides personalised health advice. You can make healthier choices to plan outdoor activities and use a cleaner walking route.

The app is developed by scientists from the Institute of the Environment at Hong Kong University of Sciences and Technology. Clean Air Network is one of the supporters on application development. Phase 1 development is officially launched in June 2019.
