Ventify helps you find out whether airing out your room will increase or decrease its humidity. Relative humidity depends on temperature and does not reflect the actual amount of water in the air. However, when ventilating, absolute humidity is what matters. That’s why fresh outside air, even with seemingly low relative humidity, can still raise the humidity indoors. Ventify converts relative humidity into absolute values and gives you a clear recommendation on whether ventilating makes sense. Convenient and automatic: Ventify supports HomeKit, current weather data, and both **Celsius and Fahrenheit**. You can select a room with temperature or humidity sensors, so Ventify automatically uses these values. Alternatively, you can define a location from which weather data is automatically retrieved. This way you save manual input and get results even faster.
