Calculator of Air

As an HVAC controls technician this app is incredibly useful. I use this app all the time. The latest update broke the display though, now the app is only rendering in the upper left-hand corner of my screen with a big black border around the rest of the screen. I’m on an iPhone 17 Pro.

I’ve been using this for a while, it works !

I need to calculate the RH% inside a house given the outside temp, outside RH%, and indoor temperature. This requires two steps. First calculate dew point of outside, then using same dew point and indoor temp, calculate indoor RH%. But this calculator erases the dew point when I’m at step 2 entering the indoor temp. I have to memorize the dew point and re-enter it. Another minor thing is it displays too many digits. P.S. The developer taught me a trick. At step 2 before entering the temp, press the dew point button first, then the dew point number will stay. I added one more star to the review.
