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.

* 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)

* Configurable digit grouping and decimal point
* Three RPN styles: direct-entry (classic RealCalc mode), buffered-entry, or XYZT rolling stack

Ratings and reviews

It's a great calculator, but I keep getting the popup message "RealCalc isn't allowed to use moblie data" right in middle of the number pad when I'm trying to type. One, everyone hates popups. Two, this is never ever an urgent matter and there is zero justification for interfering with my typing even for half a second. Three, no sh**, I set it that way for a reason. Nagging me to change it back is a sure way to earn a lifetime ban from my phone. Fix it.

Great scientific calculator! I use it almost daily! The only confusing thing is the SHIFT key. The indicator that SHIFT is on is some tiny text at the top of the display. It would be a lot clearer if the yellow labels changed place with the white labels so that the active labels were on the buttons. Then it would be obvious and intuitive that which labels were active.

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.
