PRIVACY All AI inference runs on-device using Apple Intelligence. No air quality summaries, queries, or personal data are sent to any server beyond the EPA AirNow API request itself. DATA Air quality data is provided by the U.S. EPA AirNow, Singapore NEA, or OpenAQ (a nonprofit aggregator of reference monitors). Air quality values, forecasts, and health messages come directly from official monitoring stations near your location.

v2.6.1 — Worldwide Air Quality This is our biggest release ever. Smog Report now works in ~100 countries with reference-grade monitor data, and displays the air-quality index your country actually uses. WORLDWIDE COVERAGE via OpenAQ (worldwide) + Singapore NEA (Singapore) alongside EPA AirNow (U.S.). THE RIGHT LOCAL INDEX, AUTOMATICALLY • U.S. → U.S. EPA AQI • UK → DAQI (1–10) • EU → European Common AQI (1–6) • Canada → AQHI • Singapore → PSI • India → NAQI • Korea → CAI • Australia / New Zealand → AU AQI You can also pick any scale from Settings → AQI Scale. 22 LANGUAGES The full app, widgets, Live Activities, and Apple Watch app are now translated into 22 languages including Arabic, Chinese (Simplified + Traditional), French (France + Canada), German, Hindi, Japanese, Korean, Portuguese (Brazil), Spanish (Spain + Latin America), Swedish, and more. OTHER IMPROVEMENTS • AQI gauge now displays your selected scale's native value (no more clamping non-US data to the EPA scale). • Settings → AQI Scale lets you override the country default. • Pollutant names are localized. • Live Activities and widgets all pick up the active scale. • Background refresh routes through whichever data source matches each saved location's country. PRIVACY (unchanged) Your location is sent only to the data source for your country (AirNow / OpenAQ / Singapore NEA), never to a server we operate. No account, no tracking SDK.
