# Thermodynamics Calculator vs CTE Calculator

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.

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.
