SG Air Quality
PM2.5 and PSI
Free · Designed for iPad. Not verified for macOS.
# All five regions, one glance
Singapore's North, South, East, West and Central region, each with its current 1-hour PM2.5 and 24-hour PSI reading, colour-coded so you don't have to remember what the numbers mean. Refreshed readings are available one an hour and will update in the background.
# A plain-English summary
Using Apple Intelligence, the app writes a short summary of what today's readings actually mean for your outdoor plans.
# Alerts, on your terms
Pick your own PM2.5 and PSI thresholds, choose the regions you care about, and the app will let you know when the air crosses the line.
# See where it's heading
Interactive charts for the last 12 hours, 24 hours or 3 days, for both PM2.5 and PSI. Scrub across the chart to compare every region at any point in time. Handy for working out whether the haze is clearing or settling in.
PM2.5 and PSI readings are sourced from data.gov.sg.
