Hong Kong Air Pollution

This app contains comprehensive data. And allows us to know the PM2.5 in Hong Kong according to different country standards. Can the developer keep updating it? Pls charge us if you think more information and user interface needed to update. We strongly depends your app for us to know when to wear mask or not.

As well as useful, it also shows how weak HK air quality standards are compared to other places

Guys this is perfect it gives you a good idea of when to wear a pollution mask and when it's not save to go out. One thing I'd like to see developed - a warning notification on my phone. I.e. when certain levels are high it would be nice to be able to switch on a notification .. would that be possible? In any case great going for that - love the initiative!
