# Aeriqo

> Route-level air quality for runners and cyclists. Aeriqo shows air quality segment by segment across your entire route, not just one city-wide number.

Aeriqo is a free web app for planning cleaner outdoor workouts. Draw a route or upload GPX/TCX, then get segment-by-segment AQI, pollutant details (PM2.5, PM10, O3, NO2, SO2, CO), and forecast guidance.
