Thermodynamics Calculator puts 44 thermodynamics and heat-transfer calculators — plus a library of thermal engineering reference tables — in one fast, offline app for engineers and students. Sizing a heat exchanger, checking a Carnot efficiency, or looking up the emissivity of a material? You get the formula, the result, and the reference data in seconds. WHY ENGINEERS USE IT • Solve for any variable — on most calculators, rearrange the formula and solve for whichever value you're missing, not just the "standard" output. • SI and USCS (Imperial) units — switch the whole app between metric and imperial with one tap; every input, result, and unit label updates instantly. • Reference tables built in — emissivity coefficients, thermal conductivity of common liquids and heat-exchanger materials, radiation constants, and more. • Find it fast — search plus category filters: Heat Transfer, Thermal Expansion, Radiation, Energy & Work, Dimensionless Numbers, Properties & Tables. WHO IT'S FOR Mechanical, chemical, and HVAC engineers, and thermodynamics / heat-transfer students who want quick, reliable answers without digging through a textbook.

Verdict
The clearest difference is review sentiment: Thermodynamics Calculator at 50% against Cryogenics Pro's 0%. Thermodynamics Calculator also leads on rating (4.0 vs 1.0) and in-app purchases (none vs 3). Cryogenics Pro's advantage is price (Free vs $1.99) and update cadence (every 10 days vs every 7 months). On ads, device support and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Cryogenics Pro is free to download; Thermodynamics Calculator costs $1.99 up front. Cryogenics Pro sells 3 in-app purchases, starting at $0.99 per month. Thermodynamics Calculator asks for nothing beyond the download.
Thermodynamics Calculator holds the better App Store score, 4.0 against 1.0. That said, the two scores are not equally well evidenced: Thermodynamics Calculator has 30 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 50% of Thermodynamics Calculator's written reviews are positive against 0% of Cryogenics Pro's.
Thermodynamics Calculator ships an update every 7 months, Cryogenics Pro every 10 days. The most recent releases landed on October 23, 2026 and October 25, 2026 respectively.
