SMath Studio

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

Great program for conducting engineering calculations. The ability to insert text blocks and pictures makes it perfect for both computation and communication of the results to colleagues.

Thank you for SMath. It's been a life saver.

Although it lacks some of mathcad's possibilities, it is undoubtedly an excellent spreadsheet for engineering.

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.

SMath Studio is a great alternative to MathCAD. It is small and portable. I use it primarily for structural engineering calculations and for documenting my work. Many thanks to Andrey and the other developers for this great tool.

by Eric Durham

As experienced mechanical guy, this powerful tool is extremely useful for calculation for my work activities, and amazing it is free please keep working for software crown and kick expensive mathcad away!

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.
