AntoineVP is an iPhone application that helps users calculate vapor pressure and temperature data for more than 10,000 organic and inorganic chemicals. The app uses the semi-empirical Antoine equation to provide results. Users input values for either temperature or pressure in the calculator and get corresponding values for the pressure or temperature, respectively. The app allows users to choose from different temperature units, including Celsius, Kelvin, or Fahrenheit, and pressure units, including millimeters of mercury (mmHg), Pascal, kPascal, bar, or atmosphere. It's worth noting that mmHg and Torr are equivalent units. To find a specific chemical, users can either search by Chemical Abstract Service (CAS) number or search by a common chemical name.

Verdict
The clearest difference is price: NASA at Free against AntoineVP's $0.99. NASA also leads on update cadence (every 2 weeks vs every 23 months) and ratings volume (64K vs 1). On rating, ads and in-app purchases there is nothing between them.

NASA is free to download; AntoineVP costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
AntoineVP holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: NASA has 64K ratings behind it against 1, so its average is the more settled of the two.
NASA ships an update every 2 weeks, AntoineVP every 23 months. The most recent releases landed on October 25, 2026 and October 7, 2026 respectively.
