Haze@SG: Real-time PSI Monitoring App
Haze@SG is an Android app developed by Hosay Studios that helps you monitor the Pollutant Standards Index (PSI) in real-time. The app provides hourly PSI readings based on PM2.5 concentration levels across Singapore from the National Environment Agency (NEA). This app is particularly useful during the Southwest Monsoon season from June to September when dust, smoke, and other dry particles can obscure the clarity of the sky.
In addition to PSI readings, the app also provides hourly AQI readings and PM2.5 concentrations. The app's notification feature alerts you when the PSI level reaches an unhealthy level. You can customize the notification feature according to your preference. You can also share the current AQI/PSI/PM2.5 readings with your friends and family to keep them informed and safe.
Overall, Haze@SG is an essential app for anyone who wants to stay informed about the air quality in Singapore. However, it is important to note that this app is developed without any involvement of NEA, and any inaccuracies found should not be attributed to NEA. If you have any feedback or suggestions, you can email the developers at
