### 1/5 — Inappropriate ads

*2026-05-18*

AI generated inappropriate ads

**Developer response:** Hey Sainthawk, sorry about that ad! They're served by a third-party network, so we can't control each one directly. The app's free and runs on ad revenue, but the Pro version removes all ads completely. Would really appreciate it if you'd consider upgrading — it supports the app and you won't see ads like that again. Thanks!

### 1/5 — Terrible

*2021-01-30*

Confirmed the values by plotting on a psychrometric chart and it wasn’t even close!

**Developer response:** Thanks.
Please tell me specifically how it does not fit the psychrometric chart.

### 4/5 — Review

*2020-05-23*

Excellent. Especially for free and the ad doesn’t dominate the app like most free apps. It also is t from and center in fact it sits lightly at the top and sort of blends in unnoticeably.

### 5/5 — Just what I wanted

*2022-07-31*

I have been using this app for about two month. The only fault I could find is the ads. Personally, I would like an option to pay for an ad-free version. But the developer had done a good job of minimizing the impact of the ad. I have checked the results against a thermodynamic program that I use for process simulation. The programs match up. I have found this app to be easy to use and intuitive. If one is an HVAC professional, this app and a good hygrometer are just what one needs to “get it right.” Way cool.

UPDATE: I discovered that the developer has a different version called CalcComfort that includes a pro version that deletes ads and includes additional features like Frost point for temps below freezing. Excellent.

**Developer response:** Thank you very much for using this application.
We are very pleased that you understand the purpose of the application.

### 5/5 — À great app

*2020-07-07*

I’d like to pay for This application to use it without pub

Thanks for this app. I Love it.

### 5/5 — Very Useful for Home Weather Station

*2015-10-27*

Used the app to calibrate humidity readings of a home weather station.
