## What is Absolute Humidity?

Humidity Manager is the app that helps you manage indoor humidity in a smart way, providing personalized advice on the best time to ventilate your rooms.

HOW IT WORKS

The app compares indoor and outdoor absolute humidity to determine whether opening windows will reduce or increase indoor humidity.
Simply enter temperature and relative humidity for indoor and outdoor environments, and the app automatically calculates absolute humidity and provides clear, detailed guidance.

KEY FEATURES
	•	Automatic Calculation: Uses the scientific Magnus formula to accurately calculate absolute humidity in grams per cubic meter.
	•	Smart Advice: Personalized recommendations that clearly indicate when to ventilate, with urgency levels to highlight the importance of action.
	•	Weather Integration: Automatically retrieves outdoor temperature and humidity based on your location using WeatherKit, or allows manual input.
	•	Intuitive Interface: Modern, easy-to-use design with clear visualizations for immediate understanding.
	•	Best Practices: Dedicated section with practical tips on optimal indoor humidity management, including ventilation duration and frequency, ideal relative humidity, and seasonal advice.

WHY IT MATTERS

Ideal indoor humidity should be between 40% and 60%. Excess humidity can promote mold growth and health issues, while air that is too dry may cause dry mucous membranes and respiratory discomfort.

Ventilating at the right time is essential: opening windows when outdoor air is more humid than indoor air worsens the situation, while ventilating when outdoor air is drier improves indoor comfort.

	•	People who care about indoor air quality
	•	Those with respiratory issues or allergies
	•	Families with children

TECHNICAL FEATURES
	•	Calculations based on recognized scientific formulas

### 5/5 — Ohne Schnörkel

*2026-08-11*

Genau das, was ich gesucht habe. Gemessene Innen- und Außenwerte eingeben und eine Differenz der absoluten Luftfeuchte erhalten. Perfekt wäre noch Anzeige der Taupunkte. Gleich den Euro für Premium spendiert.
