Hempel Datasheets vs Calculate Comfort Utilisation & Stats

This app calculates comfort levels by evaluating heat, cold, dryness, and moisture. You can easily adjust values using a dial. Results are visually displayed using color and emoji indicators. By inputting temperature and humidity, dew point, or wet-bulb temperature, the app calculates the following air conditions: Relative Humidity (%RH) Dew Point / Frost Point Temperature (°C DP / °C FP) Wet-Bulb Temperature (°C WB) Mixing Ratio (g/kg) Absolute Humidity (g/m³) Enthalpy (kJ/kg) Specific Volume (m³/kg) Vapor Pressure (hPa) Saturated Vapor Pressure (hPa) Discomfort Index (DI) Wet-Bulb Globe Temperature (WBGT) Comfort Indicator (18–28°C, 40–70% humidity) When within the comfort range, a visual indicator using color or emoji will appear. ■ Main Features Index Toggle (DI / WBGT) Tap the DI section to switch between Discomfort Index and WBGT. Atmospheric Pressure Input Tap the pressure icon to select from: Standard (1013.25 hPa) Sensor (reads from internal barometer) Weather Data (auto-fetched) Manual Entry (800–1200 hPa, or 23–36 inHg with Pro) Input Switching (% Icon) Switch between relative humidity, dew point, or wet-bulb temperature. In dew point mode, long-press to choose between dew point (condensation) and frost point (ice). In wet-bulb mode, long-press to select psychrometer type: 　・Assmann (ventilated, high accuracy) 　・August (non-ventilated, simple) 　・Sling (manual rotation) When below 0°C, a freeze switch appears (automatic freeze below -10°C for Sling type). You can toggle freezing manually to match actual conditions. Weather Auto-Fetch (Weather Icon) Uses location to retrieve temperature and humidity from weather data. Long-press to choose the provider: OpenWeatherMap or Apple Weather. Reset (Circular Arrow Icon) Restores default values (set in settings). Psychrometer resets to Assmann. Long-press to set your own default temperature/humidity. Info (i Icon) Opens help and purchase screen. – Pro Version Features – Unlock the following: ・Ad Removal Removes all ads. ・Unit Conversion Switch between SI and US units: 　°C ↔ °F 　g/kg ↔ gr/lb 　g/m³ ↔ gr/ft³ 　kJ/kg ↔ BTU/lb 　m³/kg ↔ ft³/lb 　hPa ↔ inHg ・Export Function Export calculation results as text. ■ Calculation Specs Saturated Vapor Pressure: Sonntag formula Vapor Pressure: JIS Z 8806 Relative Humidity: WMO standard (denominator = vapor pressure of supercooled water) ■ Notes Extreme inputs may cause errors. Values may slightly vary due to rounding and internal conversion. While accuracy is a priority, results are not guaranteed. The developer is not liable for any damage caused by app usage.
