Scientific++ Calculator for iPhone
One can spend hundreds of dollars on a decent calculator these days. Most college student pick up fancy ones for their courses. Physical calculators do have their benefit. But you can always use apps such as Scientific++ to turn your iPhone into a scientific calculator and save yourself money in the process. Scientific++ can handle fractions, quadratic systems, and a whole lot more and does not cost a whole lot.
Scientific++ has a pretty decent interface. It not only performs basic calculations, it is capable of handling fractions, degrees, equations, and polar problems. I like the fact that the left pane scrolls to offer more features. The most common operations are always where you can find them easily. The calculator comes handy for angle problems too.
Scientific++ is not the most sophisticated calculator we have tested. But it is pretty decent as a scientific calculator. It saves you from having to spend a considerable amount of money on a physical calculator.
