MADE FOR YOUR MAC
A focused menu bar app with an optional Open at Login setting, so monitoring can resume when you sign in. The app must be running to check readings and trigger alerts. An internet connection is required to retrieve new readings.
DATA AND TRANSPARENCY
Uses Singapore NEA PSI and PM2.5 data supplied through data.gov.sg under the Singapore Open Data Licence. The 24-hour PSI and 1-hour PM2.5 are different measurements; PM2.5 is shown in µg/m³. Readings reflect the source’s published updates, rather than continuous measurements at your exact location.
Haze SG Menu Bar is an independent app and is not affiliated with or endorsed by NEA. Notifications depend on your macOS notification settings. Repeated alarm audio plays through the app and may not be silenced by Focus.
