This is NOT JUST another calculator. It features:

• Beautiful math expression, the kind you see in textbooks.
• Yet easy to edit, as you do normal text.
• And no M+/M-/MR — want to use history? No problem, just ONE tap!

Well, all sound essential, right? Oddly enough, though, such a calculator never existed, until now!

FYI: There is a free Lite version (iPhone-only) for you to try before you buy.

What's New

• Now supports pop-up keypad — touch & hold on, say, the division key [ / ], and you'll know what I mean.
• By pop-up keypad, many functions/operators are added, including: abs, floor, ceil, hyperbolic functions and their inverses, fraction, and more.
• Bug fix: precedence treatment in expressions like "sin30 cos30" was incorrect in Textbook Convention.
• Other subtle bug fixes and improvements.
