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.
