ARDY puts your home's air in your hands. Ardy is the companion app for the Ardy smart ventilation system by Natural Dynamics. Pair your Ardy controller to monitor indoor air quality, control your ventilation, and see how efficiently your home is breathing — from anywhere. WHAT YOU CAN DO - See live air quality — CO₂, temperature, humidity and VOC readings from every room, updated in real time. - Control your ventilation — start or stop the system and switch to Max mode for a quick air refresh (device owners). - Understand each room — per-room airflow and sensor readings, so you know exactly where the fresh air is going. - Track trends — history charts for today or a custom range to spot patterns in your air. - Your air-quality dashboard — a clear indoor-air-quality score plus ventilation efficiency over the last 24 hours, 7 days, or 30 days. - Manage multiple devices — monitor and control every Ardy in your home from one place. SMARTER, MORE EFFICIENT VENTILATION Good ventilation means lower CO₂, balanced humidity, and fewer indoor pollutants — without wasting energy. Ardy continuously balances fresh air with heat recovery, and the app shows you what's happening and lets you fine-tune it. SIMPLE & SECURE - Quick setup — pair your device with the code shown on your Ardy controller. - Sign in with Apple, Google, or email. - Your data is encrypted in transit and stored securely. REQUIRES AN ARDY DEVICE The app works with the Ardy smart ventilation system. You'll need an installed Ardy controller to pair and use the app. Support: mail@naturaldynamics.fi
