Percentage Calculator

Percentage Calculator is an iPhone- and iPad-compatible app designed to help users solve percentage-related problems in a question-answer style manner.

The app was created using Apple SwiftUI and uses SwiftMath, a library to display TeX content.

It features seven calculation modes. It can solve basic problems like:

Given a percentage and a base value, calculate the percentage value.

However, more complex problems can also be solved.

Given a percentage value and a percentage, calculate the base value X such that subtracting the percentage from X results in the given percentage value.

The solution path is always apparent. All values can be given an unique color. An additional set of colors can be chosen to be used only in iOS dark mode.

Available in both German and English.
