This is my first Android app, and it will be available soon.

Small App with a Single Feature

The "Eschborn Shock Ventilation Humidity Calculator" is a very small app with only one feature: a model-based calculation to determine whether shock ventilation will increase or decrease the amount of water in the air, and by how much the water content (in grams) changes.

The app is based on the following assumption: During shock ventilation, multiple windows are opened for a short period of time (approximately 3 to 10 minutes), creating a draft. The model assumes that this period is long enough to completely exchange the air, but short enough that effects such as evaporation from furniture or cooling of walls can be neglected.

Suitability

This app is suitable for you only if all of the following conditions are met:

  • you are a private user,
  • you have difficulty keeping the humidity below the recommended 60% in at least one room at home,
  • you own a hygrometer (humidity meter) and a thermometer,
  • you are comfortable working with quantities,
  • and you want to use the app to determine whether shock ventilation will increase or decrease the amount of water in the air, and by how much the water content (in grams) changes.

This app is based on model assumptions. It does not replace professional advice and is not intended for construction-related or health-related decisions.

How It Works

The app works as follows:

  • Decide which "living space" you want to consider: a specific room, the entire apartment, or the whole house. Specify the corresponding floor area and ceiling height.
  • Measure the indoor temperature and relative humidity with your hygrometer and thermometer. If values differ at various locations, calculate the average.
  • Manually enter the following values for the selected "living space" in the app: area, height, temperature, and relative humidity.
  • Measure the outdoor temperature and relative humidity with your hygrometer and thermometer.
  • Manually enter the outdoor temperature and relative humidity in the app.
  • After completing these steps, the app will calculate whether shock ventilation will increase or decrease the amount of water in the air, and by how much the water content (in grams) changes.

No Additional Features

The app has no other features.

Bugs, Suggestions for Improvement, Praise and Criticism

If something does not work, if you find bugs, if you would like to suggest improvements, offer praise or criticism, or simply want to exchange thoughts with me about the app, I look forward to receiving your e-mail.

If you purchased the app and wish to withdraw from your purchase, if you are dissatisfied with the app, or if you believe that I have violated your rights, then I kindly ask you to contact me via e-mail.

I usually respond within three business days.

Help Me Test the App

Before I can publish the app on the Google Play Store, it still needs to be thoroughly tested. This is important to ensure that it works properly from the start and provides a good user experience. It is also a necessary condition for the app to be accepted for publication on the Google Play Store. If you would like to take part in this so-called "closed test," have an Android smartphone or tablet, and the app meets the eligibility requirements listed above for you, I would be very happy if you got in touch with me.
