SMath Studio

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!

Best WYSYWIG math software, with outstanding cost/effect factor! In some areas even better thought than it's commercial oponent (auto complete, very big plugin database, small program size etc). Highly reccomended.

SMath makes my job as a mechanical engineer easier. It creates much more presentable calculations which are easier to follow (compared to a Matlab script or Excel spreadsheet).

Imagine combining Microsoft Word with the ability to compute every time you press equals. Best application for your engineering documentation needs!

Excelente software para los cálculos de ingeniería, muy livano, pero bastante robusto a la hora de realizar cálculos; y su plataforma en la nube es buena.

Great tool for all engineers. It's very user-friendly and has lots of functionalities that can be further extended by installing plug-ins (it takes just a few clicks, no need for tedious file manipulations). SMath can operate on units, perform symbolic calculations and many more. Also, it has very clear interface and all formulas can be entered just like you would do on a piece of paper. What's more, the software has great community of people willing to help with various issues.
