FormulaCalculator for Mac offers users numerous advanced calculator features, including tools for finance, geometry, and unit conversions. It's not the most intuitive program we've ever used, but it's not a bad choice if you're looking for features beyond the offerings of Apple's native Calculator app.
FormulaCalculator's interface is fairly straightforward, with a number pad on the right and algebraic and trigonometric functions on the left. A drop-down menu lets users select the finance, geometry, or unit conversion libraries; once one of these is selected, an additional drawer slides out to the right displaying additional features. The finance library includes calculations for annuity loans, savings, and compound interest, while the geometry library contains tools for calculating sides and angles and the area, volume, and circumference of objects. The conversion and constants library lets users access a variety of length, volume, weight, and temperature conversions and also contains math and physics constants. It took a little bit of experimentation for us to get comfortable with FormulaCalculator; switching between features resulted in error messages until we got into the habit of clearing our previous work and entering things in the correct order. The program comes with a fairly comprehensive Help file that explains its various features. Overall, we think FormulaCalculator is a good option for users who are seeking a free calculator that offers advanced tools in a variety of different areas.
FormulaCalculator for Mac installs and uninstalls without issues.
