User reviews

Really Useful App.

This app is really useful for weather watchers. The Storm Track is best in class and the Rain Radar is also worth watching during wet weather. It works even on old Apple devices. I would give it 5 stars if it were more user friendly. The HKO has just tried to add too many functions.

Widget data inaccurate

UV index data in widget and in app main menu is different from the data in the UV index page. Widget says 1 low while inside app says 4. Or it because it only updates once every hour?

Predictable weather forecast

Been using the app ever since staying in Hong Kong. Relatively accurate weather forecast comparing to other weather forecast apps. Highly recommend!

Most Accurate Weather App in Hong Kong

Essential for every Hong Kong resident! Provides hyper-local weather alerts, typhoon tracking, and real-time radar data. The interface is clean and information is always reliable. Has saved me from unexpected rain countless times!
