CalcKit vs Custom Formulas

CalcKit lets you create your own personalized calculators. With CalcKit you can: - Design calculators using your own formulas and input labels - Enter formulas with up to seven user-defined variables - Make use of built-in trig and other math functions - Organize your calculators into convenient groups CalcKit has a simple, intuitive interface, and it comes with a set of example calculators to get you started. You can create an unlimited number of personal calculators. Each formula can be as simple or as complex as you need. CalcKit is ideal for students, scientists, engineers and others who do everyday calculations and need more than a limited set of canned formulas.

This app is easy to use, but unlike simpler apps, multiple entered values can be fed into multiple formulas and multiple output values can be displayed. The output of one formula in a group can be fed into the next by using the same variable name. Related formulas can be grouped into categories to make them easy to find. e.g. Maths formulas, Surveying formulas, Loan interest formulas etc. The order of variables displayed to the user can be changed, as can the number of decimal digits of precision shown in the output fields. You can easily share formulas with other users of the app by emailing them. Three example formulas are pre-installed with the app. In order of increasing complexity they are: slope percentage, compound interest, and point scale factor.
