Modulo Calculator is an Android app developed by MLZ that helps programmers and computer scientists calculate the modulo of two numbers. This app is designed to calculate the remainder after division of one number by another, which is often required in programming and computer science. The app supports exponential notation (^ power), decimal numbers, and calculations including inverse (^-1), addition, subtraction, multiplication, and division.

The app has a user-friendly interface, and it allows users to see how the modulo operation result differs between different modulo definitions used by programming languages, including Euclidean Modulo, Truncated Modulo, and Floored Modulo. Users can also see how many times the second number fits in the first one, and the app lets users copy the result to their clipboard. Additionally, the app supports both light and dark modes, making it easy to use in any lighting situation.
