RedCrab is a scientific calculator with a full screen formula editor. Mathematical expressions can be entered in a window similar to a piece of paper. The calculator's editor supports the entry of complex algebraic equations like fractions, square roots, exponents etc. for technical and scientific applications.

Several mathematical functions can be written on the same page and results from one expression can be carried over to the next task. The program helps explain complex tasks visually by importing drawings in bitmap format.

Not portable, check forum for details.

Smath Studio currently at Version 0.99.6671 is better and without any limitations. It is reacheable under https://en.smath.info/forum, but one should read SmathPrimer.pdf before using the program.

Thanks for making this BGM. I think I may have come across this in one of its earlier version. After re-testing it has now replaced Numculator as my go-to calculator due to the swiftness of its launch.

@billion any idea where I could find the changelog for 1.8+? Could only source up to 1.7 on the documentation site.

billon on 2019-05-21 11:44

@Specular:

v1.8 wasn't announced even on DonationCoder
Maybe v1.9 changelog is summary for 1.8 too?
Or maybe BGM himself can clear this?

By the author of Ubiquitous Player:

I've decided to stop updating this program. In 3 years I received exactly zero feedback on it, so I guess no one really uses it.

Thanks.

shnbwmn on 2016-05-17 21:37

So ... is this program being actively developed again now?

MIKLO on 2016-08-23 14:32

WOW this is still being updated I'm surprised but anytime someone is willing to improve their software 4me its a good thing. I used this some time back it does a lot of things but to me is just way to busy although it did work well when I used. :)
