HiCalc Pro (Calculator – 12 in 1) is a tremendous upgrade over the current iOS default calculator. It doesn’t just give you a few upgrades for its small price tag, but rather provides twelve different calculators in one package. HiCalc Pro provides the typical basic & scientific calculator, a currency convertor, a unit converter, a finance calculator, a date-time calculator, a constants library, an equation solver, a statistics calculator, a base converter, a graphing utility, and even throws in the typical tip calculator. HiCalc Pro calculates in three different modes, standard, string, and RPN, and claims precision up to 31 digits. The app provides a multi-line display for easy input of complicated expressions and conveniently adds an option to see your expressions in normal writing mode. The normal writing mode is a great feature for users who struggle to keep track of equations they are writing, especially when the order of operations becomes an integral part of solving a particular problem. Try an equation with a square root to best see what the writing mode accomplishes.
HiCalc Pro could be quite the handy tool for students or users in the field of mathematics and science. For such a low price, you can get the majority of features that are present in expensive graphing & scientific calculators currently on the market. I was personally blown away by the 1500 constants in the constants library, how easy it was to graph, and the depth of the statistics calculator.
