About this app

RealCalc Plus is the pro version of RealCalc, one of Android's most popular scientific calculators.

RealCalc Plus is designed to look and operate exactly like a real hand-held calculator. It has all the standard scientific functions plus fractions, degrees/minutes/seconds, history, memories, customizable unit conversions and constants. You can choose from a number of display styles and formats. It also supports binary, octal and hexadecimal calculations and has an optional RPN mode. RealCalc Plus is easy to use, but has full help included in the app.

RealCalc Plus includes the following features:
* Traditional algebraic or RPN operation
* Fraction calculations and conversion to/from decimal
* Degrees/minutes/seconds calculations and conversion
* 12-digit display
* Extended internal precision (32-digit)
* User-customizable unit conversions
* User-customizable constants
* Percentages
* Result history
* 10 memories
* Binary, octal, and hexadecimal (can be enabled in Settings)
* Trig functions in degrees, radians or grads
* Scientific, engineering and fixed-point display modes
* 7-segment, dot-matrix or standard font display
* Landscape mode
* Homescreen widget (now with RPN support)
* Configurable digit grouping and decimal point
* Three RPN styles: direct-entry (classic RealCalc mode), buffered-entry, or XYZT rolling stack

Ratings and reviews

This was the first app I ever spent money for, way back in 2010, when I got my first smartphone. I don't remember how much I paid, but however much it was, RealCalc has earned its value many times over, over the past 13 years. Every time I get a new phone, the first app that gets installed is RealCalc Plus. It's a very full-featured calculator, with chunky buttons, all the scientific functions you could ask for, and a RPN-mode. What's not to love?

I love this calculator, it has everything I need. Unit conversions, fractional calcs to decimal (and back, wow!), hex and binary math, combinational calcs, huge stack and result history, many built-in constants (you can add your own, too) and it even works in RPN! Wish I'd had this in college. Also wish I could find a similar app for my desktop. Well worth the price.

Outstanding app...love the RPN functionality as I used an HP for years that way. Would like to request functionality to switch back and forth from rectangular to polar coordinates. And also the ability to perform addition and subtraction of same. These calculations are required from time to time and have the ability to easy perform them anywhere would be tremendous. Very helpful for vector math used in a variety of scientific and engineering disciplines.
