Ratings and reviews

If you're in a thermo class, this is what you're looking for. No bs, solid UI, highly functional, and the most modest in app purchase I've ever seen. I bought the highest level of access ($4.00) out of principle because of how much time and frustration this is going to save me.

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.

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.
