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.

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 :)

Noting the two errors - still a good app.
Made a note of the two errors reported, but this is still a very useful app.
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.

Fast and Efficient
Great for Differentiating\AntiDifferentiating!
