HVAC Toolkit Ultimate

This app works well (especially given the cost) It has a few bugs when used with modern devices (notably the scrollboxes get clipped).

I bought the app to do load calcs on my iPhone . There is something seriously wrong with that portion of the app however all the other parts work fine , only problem is I need a program to do quick load calcs not to find my superheat and subcool

Missing the one item I wanted; room by room heat load calcs. It has a room by room that has ceiling as the only opaque feature active. $24 more to get the residential load calc "plus". Bummed at the cost of the first, and further by the second.
