Air, weather and lightning for each of your places.

Questions
Why not just use myENV?
myENV is NEA's free app and it covers a lot more: weather, floods, dengue, food alerts. If you want all of that, use it. HazeWatch only shows the air, weather and lightning at your four places, on one screen.
Is HazeWatch official?
No. It's independent and isn't affiliated with or endorsed by NEA. It uses NEA's open data, published on data.gov.sg.
How precise is it for my street?
Singapore reports air quality for five regions, so each place gets its region's reading. Lightning is checked against each place's own location.
What happens to my email?
It's stored only to tell you HazeWatch is open, then used for nothing else. To have it deleted at any time, email [email protected].
