SMath Studio

If you are thinking about getting MathCAD for your business or personal use you may want to try SMath Studio first. SMath Studio is a free math program with easy to use intuitive "paper-like" interface. If SMath Studio meets your needs then look no further and consider donating to promote further development of this great program. On the SMath Studio forum, the developer and forum community are very receptive to help questions, bug reports, and feature requests.

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

The most important daily-use software for engineers. Far more powerful than actual Mathcad Prime. I actually use more SMath Studio than MS Excel at work. Thank you, Andrey, for this GEM.

Succeeds where MathCad falls short. Used daily as an electrical engineer. Highly recommend.

As a student engineer, this is an amazing program to use for future engineers.

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.

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!

ein absolutes Muß für Ingenieure und Naturwissenschaftler und die, die es noch werden wollen. Ein perfektes Tool für Hochschulen aller Art. an absolute must for engineers and natural scientists and those who want to become one. A perfect tool for universities of all kinds.

As a civil engineer, over the years I have frequently used MathCAD for not only performing but also documenting calculations. With PTC dropping perpetual licensing, my recommendation to all the junior engineers I train is to give SMath Studio a serious look. While not a turnkey replacement for MathCAD, it provides most of the functionality and power at an incredible price. Already a wonderful program filling a key niche spot between a numerical calculator like Octave, and a CAS like Maxima, the expanding plugin and 3rd party development is on the rise and this project's future keeps getting even brighter. Much consideration must be given by any engineer or business before they settle on a software for adopting into the workflow. Although not open-source in the strictest sense, the development community is similar to what you would find in any first class OSS software project. The current owner of the SMath Project has also agreed to release the source code under open source license should he not be able to continue the project. So do not let the cost (your time) of learning SMath Studio and migrating your MathCAD computation sheets scare you. This project is here to stay.

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.
