Live AQI, pollen, wildfire smoke, and humidity weighed against your sensitivities — turned into a single OPEN, VENT, or KEEP CLOSED verdict for right now.
Example Verdict
Guidance only — based on public outdoor data, not indoor air. Not medical advice. Conditions change quickly; recheck before acting.
Features
One clear answer — OPEN, VENT, or KEEP CLOSED — plus the reason, read at a glance instead of buried in charts.
Tune for pollen, smoke, dust, or general air quality. The same outdoor reading can mean opposite verdicts for different people.
See when outdoor air is cleanest so you can air out your home at the right hour. Hourly forecast and verdict timeline. (Pro)
Different rooms, different people, different sensitivities. Track several spaces and profiles side by side. (Pro)
Push notifications when it's safe to open or time to close. "Air just cleared — open now." (Pro)
No account, no login. All data stored locally on device. Location is used only to fetch outdoor air data, never stored on a server.
