RealCalc gives your Android mobile device all the mathematical prowess of a traditional, physical scientific calculator. When you first use the app, you'll notice that it looks just like the real thing. The button layout and functions feel familiar, and the act of punching out calculations just seems natural. The bottom half of the screen is dedicated to number keys and common arithmetic operations (multiplication, addition, and so on), while the top half of the screen is dedicated to more complex operations like logarithms, radicals, roots, and trigonometric values. And similar to the scientific calculators we all know and love, there's a shift key that unlocks a world of other functions, including common Statistics tools like Combinations and Permutations.

Overall, we found RealCalc quite impressive. It was just as capable as a traditional, higher-end physical scientific calculator. And thanks to its realistic design, it was just as easy to use. We also loved that it could preserve the calculator state upon closing the app, which saved us from the potential headaches of accidental taps in the middle of long calculations. One thing to note is the app doesn't switch to landscape mode when your device is flipped. Perhaps this is a flaw, or perhaps it is yet another nod to the reality of an actual old-school calculator. Regardless, if you're looking to give your Android device scientific calculating powers, RealCalc is the app to download.

Developer's Description

Android's #1 Scientific Calculator. A fully featured scientific calculator which looks and operates like the real thing.Not working in ICS? Go to 'Developer options' in main phone settings and make sure 'Force GPU rendering' is disabled. An update is coming soon to fix this...Looking for fractions? Degrees/minutes/seconds? Landscape mode? You need RealCalc Plus. See elsewhere on this page for the link, or select 'Upgrade' from the RealCalc menu.RealCalc includes the following features:* Traditional algebraic or RPN operation* Result history* Unit conversions* Physical constants table* Percentages* 10 memories* Binary, octal, and hexadecimal* Trig functions in degrees, radians or grads* Scientific, engineering and fixed-point display modes* Configurable digit grouping and decimal point* Full built-in help* A complete lack of advertisingRealCalc Plus contains all these features, plus:* Fraction calculations and conversion to/from decimal* Degrees/minutes/seconds calculations and conversion* Landscape mode* User-customizable unit conversions* User-customizable constantsIf you find RealCalc useful, please consider purchasing RealCalc Plus to support further development. Thank you.FAQ:* If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc - see en.wikipedia.org/wiki/Kibibyte.* 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.Please read the help for more information.Recent changes:v1.7.2* Fixed possible crash on close-parenthesis.* Fixed possible lock-up in nCr/nPr for large numbers.* Delete key now deletes back from exponent to mantissa.* Added options for orientation setting.
