Mensa Balance is an Android app developed by Jakob Wenzel that allows users to read the current balance on their Mensa Card. The app supports cards from various universities across Germany, including Uni Bamberg, Uni Bielefeld, Uni Bochum, TU Braunschweig, Uni Bremen, and many more. If your university is not listed, it is still possible that the app will work, and the developer encourages users to try and reach out to him if they encounter any issues.

With Mensa Balance, users can easily keep track of their Mensa card balance without having to visit the card reader machines. The app provides a convenient way to check the balance on-the-go, making it easier to plan meals and budget accordingly. The app is free to use and is available for download on the Google Play Store.

Overall, Mensa Balance is a simple yet useful app that does exactly what it promises. It is easy to use and provides a convenient solution for students who want to keep track of their Mensa card balance. However, the app could benefit from more universities being added to the list of supported cards.
