Good Air Day

Open your windows when outside is perfect. Skip the heater or AC.

Good Air Day watches the conditions that matter (temperature, humidity, dew point, wind, rain, air quality, and pollen) and gives you one clear answer: Open windows, Good to open, or Keep closed.

No charts to interpret. No guessing. Just a verdict, the reason behind it, and a notification when things change.

PERSONALIZED TO YOU Tell us what temperature you like inside and any sensitivities such as allergies, asthma, or smoke. Your recommendations adjust to what matters for your air.

PINGED AT THE RIGHT MOMENT Get a notification when conditions turn good, and another when it is time to close up: rain coming, heat building, pollen spiking. Set your quiet hours so we only ping when you want.

FRESH AIR, LOWER BILLS When outside is better than inside, your windows beat your thermostat. Use the free option first and give your AC and heater a rest.
