Building a haze app
The haze has been getting worse in Singapore, and I wanted a quick way to check the PSI and PM2.5 levels. For the past few weeks, I’ve been checking haze.gov.sg in Safari, but it took a few taps and some scrolling just to find the information I needed.
I tried the official NEA app, but it offered more information than I was looking for. I explored other apps too, but very few had widgets.
All I wanted was something simple: a quick glance at the PSI and PM2.5 levels, with clear indicators showing whether air quality was normal, elevated or high. Nothing more.
Since I couldn’t find an app that met my needs, I decided to vibe-code one over the weekend.
I built an app with both Home Screen and Lock Screen widgets, so I can check Singapore’s air quality at a glance without even unlocking my iPhone!
I also decided to keep it completely ad-free. Somehow, monetising an app built around the haze just didn’t feel right.
Now I just hope Apple approves it soon, so more people can check Singapore’s air quality quickly and easily.
