About Airavo

Origin Story

Airavo was created by two avid cyclists who spent years asking the same thing before every workout during wildfire season: is the air actually safe for our lungs today?

AQI gives you a number, but not what it means for you. And with wildfire smoke now stretching across entire summers, even far from any fire, that question keeps getting harder.

For both of us, it's personal. Steve has managed asthma his whole life. Alex, a former bike racer, survived a near-fatal pulmonary embolism and now trains with lasting lung damage. We couldn't find an app that answered the one question we actually had: given my lungs and how hard I'm about to go, should I go outside right now? So we built it.

How It Works

• Airavo gives you a personalized verdict, not just a number: your local air, translated into a direct Go / Caution / No-Go message.
• Your cleanest window: the best hours to head out, plus a 24-hour forecast to plan around the smoke.
• Built on serious data: PurpleAir's dense local sensors, AirNow (US EPA) monitors, and OpenWeather's forecast, taking the more protective reading when they disagree, computed to the US EPA standard right on your device.
• Reviewed by experts: Airavo's exercise air-quality approach has been reviewed by Lance C. Dalleck, PhD (Professor of Exercise & Sport Science, Western Colorado University) and Michael S. Koehle, MD, PhD (Professor of Sport and Exercise Medicine and Director of the Environmental Physiology Laboratory, University of British Columbia).

"One of the most useful and least understood points is that risk is driven by the total inhaled dose, not intensity alone. On a borderline-air day, a shorter session can be the smarter choice than a long easy one, because exposure accumulates over time. It's good to see that principle built into a tool people will actually use."

Built for Everyone

Airavo was created for everyone who plans their activities around the AQI: Runners, cyclists, hikers, paddlers, walkers, and parents with kids outside. If you've ever stepped outside and wondered whether you should work out, Airavo is for you.

The Fine Print

Airavo provides general air-quality guidance, not medical advice. Smoke is patchy and sensors can under-read it, so if you can see or smell smoke, trust your senses. If you have a heart or lung condition, are pregnant, or have specific health concerns, follow your doctor's guidance.
