About this app

＊Weather data supported＊

A versatile humidity calculation app for everyone from general users to engineers — also suitable for agricultural applications.

This app allows you to easily calculate indicators such as the Discomfort Index, WBGT (estimated heat stress index), Volumetric Absolute Humidity (an important indicator for influenza prevention), and Humidity Deficit (HD) used in agriculture, using weather data.

You can also calculate a wide range of air properties from dry-bulb temperature (normal air temperature) and wet-bulb temperature obtained from ventilated psychrometers such as the Assmann psychrometer.
Atmospheric pressure can be entered manually.

The app supports 12 indicators across 16 calculation items, and unit conversion between Celsius/Fahrenheit and SI/Imperial units can be performed instantly by switching the temperature unit setting.…

Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.

In the app package we scanned

No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

Store update history

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.

App Store

Version 1.2.8 · 2026-08-13
- Added "Auxiliary Input Mode," allowing numeric input for Dew Point Temperature and Relative Humidity. In addition to the standard input ("Atmospheric Pressure × Dry-Bulb Temperature × Wet-Bulb Temperature"), you can now enter values using two distinct modes: • Atmospheric Pressure × Dry-Bulb Temperature × Dew Point Temperature • Atmospheric Pressure × Dry-Bulb Temperature × Relative Humidity - Added Pictogram Indicators next to the WBGT (Estimated Value) and Discomfort Index numbers to help you visually check heatstroke risk and mugginess. (For pictogram types and threshold values, please check the 9th and 10th screenshots.) - Updated the ad format from standard Adaptive Banners to…

Method and limits

What this report can and cannot show

What a missing label means

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.

Limits of this report

  • A package scan is static. It identifies code and text in one Android build. It does not measure a live ad session, test a deletion request, or count the steps needed to cancel.
  • Reviews keep their sample. A review-only charge shows distinct reviewers, the share and the sample size, and is published only once it clears that label’s published threshold. Calibration labels are machine-drafted and not yet confirmed by a person.
  • Not assessed is a state. It is never a zero and never a pass.
  • A missing label is not a clean bill of health. It means the evidence did not support one, not that the app is problem-free.
Not yet human-reviewed. A human review gives an app hands-on, recorded measurements. None has been run for this app. Hands-on inspections are not yet open.
