What's New in Calculate Comfort

5.5

July 2, 2026

• Fixed a bug that switched the app into test mode while acquiring outdoor air (temperature). Other minor bugs were also fixed. • When the atmospheric pressure mode is set to [Sensor] or [Weather], tapping the [Outdoor Air] button now retrieves it automatically. • You can now choose the saturation vapour pressure formula. (Pro) Sonntag (WMO) / Hyland-Wexler (ASHRAE) / Wagner-Pruss (IAPWS-95) / Goff-Gratch (classical) / Tetens (WMO approximation) In normal use the results differ very little. These formulas were built in for verification during development and are now available.

Cannot Use Fahrenheit

App works very well. It is disappointing one cannot change input to degrees F.

As covers content

The app is almost unusable because the banner ad covers the dry bulb temperature.

Response from developer

Thank you very much for taking the time to share your feedback. The app is designed so that the dry bulb temperature should not be covered by the banner ad. However, we will review this to ensure everything works as intended. Additionally, by upgrading through an in-app purchase, you can remove all banner ads for an even smoother experience. We hope you will give it a try and enjoy the app to its fullest. Thank you for your support!
