Let’s be honest - Singapore isn't short on places to check the haze or PSI. Between official portals and various weather apps, the data is definitely out there.
So why build another one?
Because mainstream either focus heavily on 24-hour averages (which don't tell you what the air is like right now) or drown you in cluttered tables and complex charts. When you're deciding whether to go for a run in 10 minutes or keep the windows open for the afternoon, you need immediate, actionable details.
That’s why I created airquality.hongjun.sg.
Here is what makes it different and why it might earn a bookmark from you:
1. 1-Hour PM2.5 & PSI Readings (What's happening right now)
A 24-hour average can look totally safe even if a sudden cloud of haze or localized burning just rolled in an hour ago. My site highlights 1-hour readings front and center, so you get an accurate, real-time snapshot of the air you’re breathing at this exact moment.
2. Trends for the Day
Air quality fluctuates throughout the day. Instead of just giving you a single frozen number, the dashboard shows you day trends. You can quickly see whether conditions are improving, staying steady, or worsening over the course of the day.
3. Fast, Clean & Zero Clutter
No heavy ads, no unnecessary menus, and no lag. It's lightweight and optimized for quick checking on your phone while walking out the door.
Give it a try
Whether you're planning your outdoor workouts, keeping an eye out for haze season, or just prefer a cleaner dashboard:
