Steam Tables Pro vs RMI Apps
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Steam Tables Pro
This app calculates a comprehensive range of thermodynamic properties for steam using the IAPWS-97 equations. It allows calculations based on various input parameters like pressure, temperature, enthalpy, entropy, and quality, and displays results in charts.
- Calculates properties from pressure and temperature
- Calculates properties from pressure and enthalpy
- Calculates properties from pressure and entropy
- Calculates properties from pressure and quality
- Calculates properties from saturated temperature and quality
- Calculates properties from enthalpy and entropy
- Displays results in T-s, P-h, and H-s charts
- Supports multiple units

Calculate water and steam properties with the IAPWS-IF97 equations. Choose six input combinations: pressure and temperature (p·T), pressure and enthalpy (p·h), pressure and entropy (p·s), pressure and quality (p·x), temperature and quality (T·x), or enthalpy and entropy (h·s). Find absolute pressure, temperature, enthalpy, entropy, vapor quality, specific volume, internal energy, density, and thermodynamic region. Explore heat capacities, speed of sound, the Cp/Cv ratio, vapor volume fraction, and transport properties. Save states to compare results and plot points on T–s, p–h, and h–s diagrams. Choose the units you use in study or work. Pressure units explicitly indicate absolute pressure, such as bar(a). Learn inside the app with a usage guide, essential concepts, explanations of each property, and worked examples for boilers, turbines, and valves. Explore boiler superheating, turbine isentropic efficiency, and constant enthalpy during throttling, with T–s and p–h diagrams. The calculator, guide, and tutorial are available offline in English and Portuguese.
