Primitive and full of typos

This primitive app is just HTML pages. The equations are not typeset, they wrap annoyingly, and the app cuts off the last line in every page. It is full of poor grammar and glaring typos, which puts the copied data in question. No sources are given either. As for the writing, the Second Law discussion is a muddle. Don't bother with this app.

Developer Response ,

Hi, We have improved the app and added more content over the years. Please send us your feedback through the feedback option in the app. Thanks.

I'm a student and this is helpful but there is a lot more that could have been included. Hopefully updates will include better organization and more tables for conductivities and convection coefficients.
