Find your best outdoor window.
Weather comes from Apple WeatherKit on your iPhone. AQI is evaluated with US AQI guidance and visible source attribution.
WeatherKit + Open-Meteo AQI
GoWindow can request AQI for global coordinates and interprets air quality with the US AQI scale for exercise guidance.
On-device WeatherKit weather
Your iPhone gets weather directly from Apple WeatherKit with no weather relay through our backend.
US AQI risk bands
Air quality is interpreted with US AQI categories for outdoor exercise decisions.
AQI confidence + source
Each AQI readout includes provider attribution and confidence language for modeled conditions.
Window-first UX
Open the app and get the best two-hour outdoor window without chart hunting.
Data pipeline transparency
Weather path
Precise location stays on-device for Apple WeatherKit weather fetches.
AQI path
Coordinates are sent to the GoWeather backend only to request AQI from the active air-quality provider.
Provider attribution
MVP AQI defaults to Open-Meteo where available; provider labels and links are shown in-app.
How it works
Allow location on your iPhone
GoWindow uses location permission for on-device WeatherKit weather and local AQI lookups.
Fetch weather + AQI context
Weather is fetched directly with WeatherKit, while backend AQI requests use coordinates only for air quality.
Follow your window
See your ranked outdoor window with AQI confidence and source details.
AQI confidence note
AQI can be modeled and station coverage varies by area. GoWindow shows provider attribution and favors conservative guidance when confidence is lower.
