About Haze Day (copy-ready)

Haze Day (haze.day) is a free, ad-free haze service for Southeast Asia on the web, as an installable app and as a Telegram bot. It shows the National Environment Agency's official readings for Singapore and clearly labelled model estimates for 79 places in 11 countries, and turns them into practical advice for exercise, school, commuting, home and pets in English, Chinese, Malay and Indonesian.
