Know the air you breathe
mySifu shows live air quality (AQI) readings from monitoring stations across Malaysia, and alerts you when the air near you gets worse.
Everything you need, at a glance
Live AQI near you
See the reading at your nearest station as soon as you open the app, with colours that follow the official DOE scale: Good, Moderate, Unhealthy, Very Unhealthy and Hazardous.
Explore every station
Browse stations by state, sort by worst air or nearest to you, search by name, or find them on the map.
Alerts that matter
Set rules for any place you care about. mySifu notifies you when the AQI crosses your threshold, and optionally when it drops back down.
Trends and pollutants
Check 24-hour and 7-day trends, health advice for the current level, and pollutant readings for each station.
Your places
Save the stations for home, work or school to your Today screen and reorder them however you like.
