PSI 3-hr Premium - SG Haze

We recommend setting this app to auto-update to keep the best working version running.

This is the premium, ad-free version of PSI 3-hr application. PSI 3-hr Premium comes with 3-hr PSI Reading widget feature not available in the free, ad-supported version. With the PSI reading widget, you can skip the step of even pressing the app icon, the widget updates itself every 30 minutes if Internet connection is available. Alternatively, you can tap the widget to force an update.

**NEW: There is now a 24-hr PSI Reading widget too! Now you can also check the 24-hr PSI Readings and PM2.5 values straight from your home screen. That's not all, you can customize its background and text colour too!

Check the 3-hour average PSI reading in Singapore provided by National Environmental Agency(NEA) using this app! PSI 3-hr allows for a convenient and timely way to check the latest PSI reading released. The PSI reading will be updated hourly based on NEA's 3-hour PSI readings. Keep up to date with the haze condition, and take care!
