Airavo

Free on iPhone. Wildfire smoke now covers whole summers. Airavo reads your local air and tells you when it's safe to head out, tuned to your lungs and effort.

AQI gives you a number. Airavo gives you the answer: a clear Go, Caution, or No-Go for going outside, tuned to your lungs and how hard you plan to go.

Know before you head out: is the air quality actually okay for you today? Built by a lifelong asthmatic and endurance athlete who was tired of guessing during wildfire season, Airavo turns messy air-quality data into one honest call you can act on in a second.

WHAT AIRAVO TELLS YOU • Go / Caution / No-Go: a personal verdict, not just a number • Your cleanest window today, the best hours to get outside • A 24-hour forecast so you can plan around the smoke • PM2.5 (smoke), PM10 (dust, pollen), and ozone at a glance • A morning heads-up and an alert when a clean window opens

TUNED TO YOU Tell Airavo how sensitive your lungs are and how hard you're going. An easy recovery walk and an all-out interval aren't the same exposure, and Airavo adjusts the verdict to match.

BUILT ON SERIOUS DATA Airavo blends PurpleAir's dense local sensors with AirNow (US EPA) official monitors and OpenWeather's forecast, and when sources disagree, it takes the more protective reading, because under-reading smoke is the dangerous direction. The Air Quality Index is computed to the US EPA standard right on your device.

Airavo's exercise air-quality approach was reviewed by Lance C. Dalleck, PhD, Professor of Exercise & Sport Science at Western Colorado University.

FOR EVERYONE WHO PLANS AROUND THE AIR Runners, cyclists, hikers, paddlers, walkers, and parents with kids outside. If you've ever stepped outside and wondered whether you should, Airavo is for you.
