A free app for Android, by MATIS 1 - Goethe University.
MathCityMap is a free application that lets you create and solve math trails. This is a great app for students, teachers, and parents who want to explore the world of mathematics from a point of view. The idea is simple: you take a number of points and create a path between them. The app will then automatically provide you with a route that you can follow and the answers to the math problems you encounter along the way. In addition, you can also find a number of mathematical hints that can help you solve the math problems if you get stuck.
What is MathCityMap?
MathCityMap is based on the math trail idea introduced in Melbourne, Australia. It is a simple app for creating and following a path between two points in space or time. You can use it for educational purposes, for example, to help you learn the concepts of trigonometry, and statistics, or to prepare for a math exam.
