I have used MathCAD since 1997. Loved it. I used to work for the Nuclear Industry in Canada, and we had these long calculation sheets fully written in MathCAD. As an independent researcher, I also had a student version which I could simply purchase from a campus bookstore as a CD. A few years later, disaster struck! A greedy corporate entity purchased MathCAD and destroyed it. A tool created for engineers by engineers with engineering in mind was destroyed by MBAs with only money in their minds. I was helpless until I discovered SMath. I was amazed at how SMath could do so many things with the installation file being just a few MB! And Andrey simply gave it away to us for free!! SMath has truly filled the void left by the now-extinct "old MathCAD". The fact that SMath is not bloatware and gives us researchers exactly what we need are reasons enough to call Andrey a genius. My dear Andrey, many of us are out there in various parts of the world quietly blessing you for helping us do our research calculations. You are a noble soul with a spirit that cares for a better world. Trust me, you have in your own way made our world a better place to live through SMath. God bless you. I shall surely donate an amount as a symbolic gesture for your great work. Please continue to serve the world and may God bless you with good health, a long life, peace, prosperity, and a sound mind that scientifically contributes for as long as you live and pave the way for your glorious legacy long after we are all gone.

Great software. Easy to use. Looks nice.

I've used this software for several years and can not use anything else for work. I'm a mechanical Engineer and use this for any calculations I do. 1) To show and check my work 2) to set values and write descriptions so I can reuse my formulas for other projects. This is better than any calculator. Thank you Smath for such a great software.

Probably the best free math program out there. As a mechanical engineering student, so many calculations can be almost entirely automated using SMath Studio.

Found out that this software is as powerful as commercial softwares. Many thanks Andrey.

This program helped me in solving a lot of my mechanical problems related to gears, design standards & structural problems. Now we can run it on our mobiles also. Thanks for this useful program.

This tool is amazing. It helped me on my university more times than i can imagine.

I use this program on my everyday civil engineering calculations, and I highly recommend it!

Très bon logiciel de calcul, avec de nombreux plugin pour tous les usages. Une fois qu'on s'habitue, on ne peut plus s'en passer. Je le recommande vivement. Outre les fonction mathématiques, Il est possible d'utiliser de nombreuses bibliothèques, comme par exemple la bibliothèque Coolprop pour les données thermodynamiques, ce qui permet d'avoir un outil très évolué pour faire et expliquer des calculs très rapidement.

Excellent software, a great job, we must support with financial contributions. Good job Andrey and the sponsors and creators.
