JeffInCR,
Found another error
In the complex algebra section, (a+bi)(a-bi) is shown as equalling a*a-b*b (a squared minus b squared). That would be true if not for the fact i*i=-1, making the correct answer a*a+b*b.
I couldn't find a way to submit a comment to the author, either here, nor on his blog. A major oversight on his part, I believe.

Found Error
Hard to get a hold of author. Left blog post on his site but no response. I purchased your product (not the free version). I was showing it to the other students, and I got an approval from my professor to use this during a quiz. He overlooked it and said to not use it now because he caught an error and cautioned me that other errors may exist.
The error he found was in the Algebra & Geometry section, Operations, and its the (a+c)/b = a/b + a/c .

Munkypoo7,
Easily one of my best buys!
This app with the latest update rocks! Much easier on the eyes now, still just as functional, even more so now!
Keep up the awesome work :)

Lisztian,
Noting the two errors - still a good app.
Made a note of the two errors reported, but this is still a very useful app.
eyeonthescreen,
What's with the font size?
Although Formulus is replete with all the formulas I would want, and then some, the screen font sizes are tiny tiny tiny. barely legible. And there are no guidelines on using the formulas. Not even the variables are defined.
I'm not sure who the users are intended to be, but the casual mathematician or scientist, especially one with eyesight issues, will find this app hard to use.
