# Chemical Engineering AppSuite HD vs Thermal Engineering Calc

Chemical Engineering AppSuite HD and Thermal Engineering Calc both sit at 4.6 stars, but that hides the real split: 86% of Chemical Engineering AppSuite HD's written reviews are positive against 50% of Thermal Engineering Calc's. Chemical Engineering AppSuite HD also leads on update cadence (every 2 months vs every 15 months) and ratings volume (81 vs 6). On rating, ads, in-app purchases and device support there is nothing between them.

Chemical Engineering AppSuite HD costs $0.99 and Thermal Engineering Calc $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

On the App Store both sit at effectively the same score — 4.6 for Chemical Engineering AppSuite HD against 4.7 for Thermal Engineering Calc. That said, the two scores are not equally well evidenced: Chemical Engineering AppSuite HD has 81 ratings behind it against 6, so its average is the more settled of the two. Written reviews are what separate them: 86% of Chemical Engineering AppSuite HD's written reviews are positive against 50% of Thermal Engineering Calc's.

Chemical Engineering AppSuite HD ships an update every 2 months, Thermal Engineering Calc every 15 months. Both last shipped on November 1, 2026.
