FormulizeIT Formula Calculator vs Custom Formulas

Turn the formulas you use often into calculators you can use again. Write an expression, name its inputs and change the values whenever you need a new result. Create your own formulas for project quotes, shopping discounts, material area or coffee ratios. • Create, edit, save and delete your own formulas. • Give variables clear display names and optional default values. • Reuse saved defaults and copy numerical results. • Use supported mathematical functions, including square roots. • Choose a light or dark appearance and your interface language in Settings. For example, save A * B. Enter 6 for A and 80 for B to get 480, then change the inputs and calculate again. Formula editing and calculations work offline. Formulas and settings are stored locally on your device. No account is required. Available in 19 interface languages. Requires iOS 15 or later on iPhone. Updating from an earlier version? Install the update over the existing app. Deleting the app may remove its local formulas and settings.

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.
