HazeWatch SG

Check Singapore's air quality in a second. HazeWatch SG shows the latest readings from the National Environment Agency, published hourly on data.gov.sg: • 24-hr PSI for the North, South, East, West and Central regions, with the health band for each • 1-hr PM2.5 for every region, useful for deciding about a run or a walk right now • What today's reading means for you, in the official NEA/MOH activity advice • Home Screen and Lock Screen widgets, so you can check the haze without opening the app • A chart of the last 24 hours so you can see whether the haze is getting better or worse • The activity guide for healthy people, the elderly, pregnant women and children, and people with heart or lung conditions • Quick links to haze.gov.sg, NEA, HealthHub, MOE and MOM for official advisories Every reading shows the hour it is for, and the app tells you clearly when readings are out of date or can't be updated. The latest readings stay on your phone so you can still see them offline. No account, no ads, no tracking.
