This application allows you to help in checking the existing and planning future isolation. After entering data on the temperature and humidity of the air and selecting all layers of the enclosing structure (starting from inside the building and ending with the exterior trim of the facade or roof) in the Thermal Transmittance Calc, you will receive information on all likely heat losses, as well as possible problems with humidity. A schedule will be built, according to which you can track how the temperature and humidity will change and where the dew point in the layers of the structure will be. - Easy to use, enter all the data and immediately get the results. - Ability to enter the temperature in both Celsius and Fahrenheit. - Ability to enter the size of the layer in centimeters and inches.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
