"Turn your Android into a real scientific calculator"

Reviewed by / May 31, 2011

RealCalc Scientific Calculator is a fully featured calculator for those who need to make more complex calculation

The default Android calculator will fall short for those who need to make complex calculations. RealCalc Donate help you out in this way by allowing you to perform formulas and functions (sin,cos,tan...). Thus, you will be able to calculate percentages, binary, octal and hexadecimal terms, functions in degrees radians or grands among many others. What's more, it displays in scientific, engineering and fixed-point modes, as well as RPN mode. It allows you to keep even 10 memories. Especially useful is the data size conversions in multiples of 1024 (Kb, Mb, Gb...).

This is the paid version of RealCalc Scientific Calculator (£1.99). There's also a free version if you want to give a try first.

RealCalc Donate has been developed by Quartic Software, who has just launched the free and paid version of this calculator. It's considered one of the best scientific calculator on the market though.

If you're one of those who daily needs to make some complex calculations, there's no need to buy a scientific calculator: you can download it from here. It's as the same as having a real one but taking advantage of your phone potential. A must have on this issue.

Developer's original description available here
RealCalc Plus is the enhanced version of Android's #1 Scientific Calculator, RealCalc - a fully featured scientific calculator which looks and operates like the real thing.

RealCalc Plus includes the following features:
* Traditional algebraic or RPN operation
* Fraction calculations and conversion to/from decimal
* Degrees/minutes/seconds calculations and conversion
* Result history
* User-customizable unit conversions
* User-customizable constants
* Percentages
* 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
* Landscape mode
* Configurable digit grouping and decimal point
* Full built-in help

* If there is no menu button, try a long-press on the 'recent-apps' or 'home' key to bring up the menu.

* If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc - see

* If the percent key appears to give wrong answers, make sure you are pressing '=' at the end, e.g. '25 + 10 % =' will give 27.5.

* If sin/cos/tan functions don't give the answer you are expecting, make sure you are in the correct angle mode. Degrees, radians and grads are supported, indicated by DEG, RAD, GRAD in the display. Use the DRG key to change mode.

* If any of the digit keys are disabled, or the decimal point doesn't work, or you have answers with letters in, or basic arithmetic appears to be wrong, then you are in binary, octal or hexadecimal mode. Press DEC to return to decimal operation. If you don't need these modes, please make sure that 'Enable Radix Modes' is disabled in the settings.

* If you can't find HEX, BIN or OCT modes, go to the settings and make sure that 'Enable Radix Modes' is checked.

Please read the help for more information.

Recently changed in this version

* Fixed bug in display of small negative DMS values.

    I don't know why I never upgraded before! It's so much better than the built-in calculator on Android. I use this app daily.
