Air quality

Real-time and historical air data for your exact location.

Your home

Track mold risk, water source, and indoor hazards.

Humidity, home age, ventilation and what's coming out of your tap.

Food system

See how your diet and food sources connect to how you feel.

Log meals in seconds and spot what lifts you up or drags you down.

Neighborhood

Green space, walkability, heat, and local pollution history.

The bigger picture of where you live, and how it shapes your days.

How it works

  1. 01

    Build your environment profile

    Enter your location and a few details about your home. Terrair pulls in public data to build your baseline.

  2. 02

    Do a 60-second daily check-in

    Log your energy, symptoms, mood, and what you ate. Takes less time than brushing your teeth.

  3. 03

    See the patterns

    "Your energy is lowest when AQI exceeds 80." "You sleep better after days with 20+ min outside." Real insights, not guesses.

  4. 04

    Get one actionable nudge

    Not a wall of data, just one thing you can do today based on your environment.

Real insights, not guesses

The kind of thing you'll start to notice.

After a few weeks of check-ins, Terrair lines up how you feel with what was happening around you. Here's what that might look like.

Air Your energy is lowest when AQI exceeds 80.

Grey line is air quality. Green is your energy.

Neighborhood You sleep better after days with 20+ min outside.

Green bars are nights after time outdoors.

Today's nudge Humidity is up indoors. Crack a window for 15 minutes.

One small action, based on your home and today's conditions.

Why Terrair

You track your body. Nobody tracks your surroundings.

The air you breathe, the home you live in, the food you eat and the streets you walk all shape how you feel. Until now, none of it showed up next to your health.

FAQ

Questions, answered.

When does Terrair launch?

We're building Terrair right now. Join the waitlist and you'll be among the first to hear when early access opens.

What data does Terrair use?

Terrair combines public environmental data for your location (like air quality, heat and local pollution history) with a few details you share about your home and your quick daily check-ins.

Do I need a wearable or air sensor?

No. Terrair builds your baseline from public data and your check-ins. We'd like to connect with devices you already use down the road.

Is my health information private?

Yes. Your check-ins belong to you. We won't sell your personal health data, and we'll be clear about how everything is used before launch.

Is Terrair a medical app?

No. Terrair helps you notice patterns between your environment and how you feel. It isn't a diagnosis. Always talk to a doctor about health concerns.

How can I help shape it?

Join the waitlist. We'll reach out to early members for feedback as we build.
