# Physics Toolbox Sensor Suite vs Thermal Transmittance Calc

The clearest difference is rating: Physics Toolbox Sensor Suite at 4.7 against Thermal Transmittance Calc's 4.1. Physics Toolbox Sensor Suite also leads on ads (none vs shown) and update cadence (weekly vs every 11 months). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Physics Toolbox Sensor Suite sells 1 one-off in-app purchase and Thermal Transmittance Calc sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Physics Toolbox Sensor Suite holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Physics Toolbox Sensor Suite has 1.8K ratings behind it against 11, so its average is the more settled of the two. Written reviews point the same way: 81% of Physics Toolbox Sensor Suite's written reviews are positive against 75% of Thermal Transmittance Calc's.

Physics Toolbox Sensor Suite ships an update weekly, Thermal Transmittance Calc every 11 months. The most recent releases landed on November 11, 2026 and November 6, 2026 respectively.
