I'm glad to see a mobile app for computing thermodynamic properties of refrigerants. That said, the user interface could use some improvement. 1. Id like to see a "clear" button to clear entries. I have trouble changing values. I get an error message that it requires two values after I enter the first new one, and can't figure out how to add the second one. 2. I can't get the delete state button to work. But this is a much needed app for engineers. Good job, and please keep improving it.

Hi Martin, thanks for your suggestions! Watch the help video to calculate a state. To delete it, select the "Delete" tool and touch the state on the graph. I don't have many characters available in these replies, please write me a mail and I will help you.

This is an excellent app designed for person who are looking for an easier tool to appreciate thermodynamics principles. I am currently using it with the refrigerant substance plugin and it has been working flawlessly. Just want to say a big thank you to the creators, for your hard work in helping many to appreciate thermodynamics more. As we know thermodynamics is not an easy subject.

so far it works well. i bought the professional version but it does not seem to have changed anything, and i don't know how to check what version i am using; i was looking for the wizards and can't find them. i think i just wasted the purchase...
