UNDERSTAND YOUR AIR. KNOW WHAT TO DO NEXT. Terrestream is the companion app for Terrestream indoor-air sensors. See what is changing in your home, understand the outdoor conditions that matter, and get a practical next step. Before you open a window, Terrestream considers both sides of it. Indoor readings and outdoor air quality, smoke, pollen, and weather help you decide when to ventilate, run filtration, investigate a possible indoor source, or keep watching. YOUR HOME, AT A GLANCE Today brings together your home's Air Index, the room that needs attention, and current guidance. Home Screen widgets put room air, whole-home conditions, window guidance, and comfort within easy reach. Choose the sizes and rooms that suit you, then tap through for more detail. Reading ages and unavailable states help you tell recent information from an older observation. AIR INSIGHTS ON YOUR WRIST The Apple Watch companion makes it easy to check your home and rooms, review window guidance, and follow an airing session. Add Terrestream to your Smart Stack or a supported watch face for quick access. The Watch app works with Terrestream on your iPhone. SEE WHAT CHANGED Compare rooms and explore 8h, 24h, or 7d of history. Inspect actual readings, choose the signals you want to see, and zoom into a change. Air-quality signals and temperature, humidity, and pressure share one timeline, with separate scales. A weekly heat map opens at the latest available reading and helps reveal patterns over time. Notification history brings your recent messages together by room and time. Review the original message and its recorded follow-up without confusing an earlier alert with today's conditions. GUIDANCE THAT FOLLOWS THE EVIDENCE Terrestream connects readings, room differences, and changes over time to explain possible causes and suggest useful actions. It distinguishes a brief rise from continuing accumulation or recovery, and builds ventilation history from independent CO₂ declines. These patterns help guide investigation; they do not identify a specific chemical or prove a ventilation fault. Use the Air view to compare outdoor conditions and forecast windows before bringing outside air in. Temperature and humidity are considered alongside air quality. Wildfire-smoke information and indoor particle readings help inform advice about closing windows and running filtration. READINGS THAT MATTER Follow CO₂, calculated IAQ, particles, VOC and NOx indices, temperature, humidity, pressure, and ambient light. VOC and NOx are relative indices that show changes over time; they do not identify individual chemicals. Pair a compatible sensor over Bluetooth, connect it to Wi-Fi, organize your rooms, and manage notification preferences and device controls. Home Assistant and MQTT integrations connect your sensor with compatible local dashboards and automations. The basic mobile app is included with your sensor. An optional Pro subscription adds longer history and advanced insights. YOUR PRIVACY Location access is optional. See our Privacy Policy for details about the information we collect, how service providers help operate Terrestream, and your privacy choices. WHAT YOU NEED Indoor readings require a compatible Terrestream sensor, sold separately, and a Terrestream account. Cloud features require internet access; the sensor uses 2.4 GHz Wi-Fi and Bluetooth during setup. Outdoor information varies by location, availability, and freshness. Widget refresh timing is managed by the operating system. Terrestream is informational, not a medical or life-safety device. It is not a smoke, fire, carbon monoxide, radon, or gas-leak detector. Keep your required alarms and do not rely on Terrestream in an emergency.
