Mold & Humidity Risk Meter

Mold & Humidity Risk turns damp, condensation and mold risk into a clear number you can act on — a mold-risk score, dew point and humidity tracker for Android.

Damp, condensation and mold all start the same way: air holding too much moisture. This app reads local outdoor conditions, lets you log indoor temperature and humidity by room, and tells you plainly whether now is a good time to open the window.

▶ MAIN FEATURES
• Mold-risk score — a single dial from Low to Severe
• Dew point calculator — indoor and outdoor dew point
• Humidity tracker — indoor and outdoor humidity in one view
• Per-room log — bathroom, basement, bedroom and other damp-prone rooms
• Ventilation window advisor — tells you when airing out actually helps
• Condensation calculator — check if moisture will form on a cold window, wall or pipe
• Burst-airing (Stosslüften) guidance for fast, efficient ventilation
• Works fully offline with on-device room logs

▶ HOW TO USE
1. Open Mold & Humidity Risk and allow location for local outdoor data
2. Enter your indoor temperature and humidity from a room thermometer or hygrometer
3. Check your mold-risk score, dew point and ventilation advice
4. Log each room and follow the tailored tips

▶ WHO USES MOLD & HUMIDITY RISK
• Renters and homeowners dealing with damp or mold
• Anyone with a humid bathroom, basement or poorly insulated wall
• Allergy sufferers and dust-mite-sensitive sleepers
• Landlords and tenants documenting damp conditions
• People deciding when to ventilate instead of guessing
• Anyone tracking indoor humidity and dew point at home

Note: Outdoor humidity and dew point are model estimates for your area, not a sensor reading in your room. This app gives guidance, not a guarantee against mold.
