TScalc Scientific Calculator Downloads & RevenueTScalc Scientific Calculator · App Store

TScalc is a scientific calculator where you type the whole expression, just as you would write it.
It is a rebuilt iPhone version of a calculator the developer originally made for Pocket PC in 2001.

TYPE EXPRESSIONS AS YOU READ THEM
Enter something like "sqrt(2) + sin(30)" in natural order. While you type, the result appears as soon as the expression can be calculated.
Implied multiplication such as 2pi or 3(4+1) works, and a missing closing parenthesis at the end is closed for you.

EDIT PAST CALCULATIONS
Your calculations and answers stay on screen. Tap one to bring the expression back, change a single number, and calculate again - no retyping.
The latest 100 calculations are kept and can also be opened as a list.
