Good app

Im moving to Singapore soon. After having spent the last 10 years living in China, I've gotten used to checking on the air quality every day. This would be one I'll be using when I'm there.

This app captures the SG haze conditions in 1 screen shot and saves me the trouble to look at multiple NEA website. Also, it presents the info in a pictorial format - a pictures saves a 1,000 words. Good job!
