VaporSill: Damp Planner

VaporSill turns room, humidity, and surface-temperature readings into a clear condensation evidence record.

Create a home workspace and add rooms. Record air temperature, relative humidity, measured surface temperature, surface location, observations, notes, and an optional photo reference. VaporSill calculates dew point, absolute humidity, and the margin between the surface and condensation conditions, then presents the result in a thermal surface atlas.

Use the intervention lab to model changes in air temperature, humidity, surface temperature, or ventilation time without overwriting the original reading. Save useful scenarios beside the evidence that produced them.

For outdoor context, search for any city or postal code. VaporSill compares your latest indoor reading with public Open-Meteo hourly temperature and humidity data so you can see when outdoor air may carry less moisture. No device location is requested, and cached forecast results remain available if the connection drops.

Export a readable PDF brief for a conversation with a landlord, contractor, or building professional. Create and restore a complete JSON backup through Android's document picker.

VaporSill is a screening and documentation tool, not a mold test, building diagnosis, medical device, or promise that a particular action will solve a moisture problem. Use suitable instruments and seek qualified inspection when damage, persistent damp, or health concerns require it.
