HiAir
Heat & Air Safety Assistant

Know when the air is safe for your body

HiAir combines heat, humidity, air quality, and personal sensitivity into clear daily guidance — so you can plan walks, workouts, ventilation, and outdoor time with confidence.

Wellness guidance only — not medical advice. iOS & Android coming soon.

The gap

Weather apps show data. They don't answer your question.

Most apps tell you the temperature or AQI number — but not whether it's right for you, your child, or your afternoon run.

Can my child play outside?

Heat, humidity, and pollution affect kids differently than adults — timing matters.

Is it safe to run tonight?

Ozone and heat index can spike when the sky looks fine. Plans need context.

When should I air the room?

Opening windows at the wrong hour can let smoke or traffic pollution in.

Why does today feel harder?

Combined heat stress and air quality affect breathing comfort — not just one metric.
