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.
