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.

La aparición del proyecto Smath, cubre un vacío que existía en el ámbito del software gratuito para Ingeniería. Es un proyecto que llegó para quedarse, ya que permite logros muy buenos a quienes utilizan esta herramienta. felicitaciones a Andrey y el gran equipo de colaboradores que cada uno con su aporte desinteresado hacen crecer esta aplicación que ya podemos caratular como de uso profesional

I strongly encourage professionals who use the software for commercial purpose to donate. SMath Studio, in my opinion, is better suited for documenting engineering calculations than MathCAD Prime 3, which is commercially developed, and is considered to be the software of choice by many.
As engineering professionals, we all pay yearly professional license fee; if we donate a fraction of that fee to Andrey it will let him to continue working on this extremely useful and functional tool.
Thank you, Andrey! Long Live SMath

I have been wishing for a sensible alternative to the free version of MathCAD for a long time. I find such software a crucial tool for writing technical-paper-style documents with live formulas and units carried throughout. I am so happy to have found SMath Studio as it is not just a completely free, fully featured alternative, but I find it to be much better in that it is tiny, is easier to use, has nice community support and has nice expandability by others (through plugins). It has features I've always wanted like setting of number of significant digits (not just number of decimal places), easier typing of subscripts, better plotting (via the X-Y Plot plugin), ability to include other SMath files (like my own units definitions), the very innovative and helpful "dynamic assistant", the ability to assign values to variables *after* the writing of a formula, no watermark across each page, and many other improvements that I have yet to discover. Since I am so pleased, I just donated $100 which I feel is a more reasonable amount for software like this. Thank you, Andrey!

SMath Studio in the Cloud is ideal to show calculations to my students. They only have to click at the internet hyperlink. Teacher at school of mechanical engineering, bachelor level.

Smath is a very simple program to use. It´s similar to Mathcad and it´s free.
I use it for my spreedsheets at work.
I recommend it, without a doubt.

SMath Studio in publications
The functionality of the program can be expanded through the installation of plug-ins created by third-party developers and companies, as well as those prepared by the SMath LLC team. Most plug-ins are open source and can be modified if necessary.

Please note: - There are some known bugs with Worksheet scrolling - will be addressed soon;
- There are some UI issues on environment with high DPI (some Custom plug-ins may not be scaled correctly).
Please use the following to disable high dpi support if required:
 To all developers: As you may notice starting from build 0.99.6955 SMath Studio supports high DPI and in order to scale Regions correctly we have to introduce new requirement: - Plug-in must use SMath.Drawing.Graphics instead of System.Drawing.Graphics everywhere.or - All Fonts created by the plug-in must have GraphicsUnit.Pixel specified as a unit and size must be multiplied by 96f / 72f in order to convert Points to Pixels.All existing plug-ins should be updated according to this requirement as everything looks ok while system is configured to have use 96 DPI, but in all other cases scaling of Fonts in plug-ins is incorrect. All modern platforms like iOS, Android, UWP have Pixel specified as a unit by default, so this issue appears on Windows machines only (we have it on Linux as well because of Mono). Please let me know in case of any related questions. If you are not able to perform changes by yourself - just let me know and I will update plug-ins by myself. Best regards, Andrey Ivashov.
