### 4/5 — Works well. Convenient.

*2023-07-16*

This app is useful for calculating residential heat index without having to connect to wifi. 
I use the screen that allows you to input relative humidity rather than dew point. 
However, I suggest the decimal point and backspace keys be boxed in like the number keys are to make them standout better.
