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 price: CTE Calculator at Free against Thermodynamics Calculator's $1.99. CTE Calculator also leads on rating (5.0 vs 4.0) and iOS requirement (13.4 vs 16.1). Thermodynamics Calculator's advantage is ratings volume (30 vs 1) and update cadence (every 7 months vs every 15 months). On ads, in-app purchases and device support 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
CTE Calculator is free to download; Thermodynamics Calculator costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
CTE Calculator holds the better App Store score, 5.0 against 4.0. 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.
Thermodynamics Calculator ships an update every 7 months, CTE Calculator every 15 months. Both last shipped on October 23, 2026.
