FrischluftCoach

Know when opening the window can improve your indoor climate. FrischluftCoach combines your room readings with outdoor conditions to help you choose when to ventilate. Its clear dashboard puts the next useful action first, followed by your rooms and the data behind the advice. YOUR READINGS, YOUR SOURCE Enter indoor temperature and humidity manually or connect compatible HomeKit sensors. For outdoor readings, choose weather at your device’s location, a HomeKit sensor placed outdoors, or weather for a fixed location. Search by ZIP code, city, or street to keep your weather tied to home while you’re away. The app can also use your saved location for weather if your outdoor sensor is temporarily unavailable. ADVICE BASED ON MOISTURE FrischluftCoach considers the moisture content of indoor and outdoor air, temperature differences, and your chosen humidity targets. Adjust maximum outdoor temperature, ventilation mode, and daytime-only advice to suit your home. WIDGETS AND A FRIENDLY FIRST START Keep ventilation advice and your active timer on the Home Screen with two widgets, each available in small and medium sizes. Tap a widget to open the relevant app screen. An illustrated, gently animated introduction explains the essentials and helps you add your first room.
