Mensa is a free Android app developed by iMensa that provides access to the menu of over 500 campus cafeterias and restaurants in more than 190 cities across Germany. The app allows you to check what's on the menu for lunch while you are still in class. Once you have accessed the menu, you can use it offline for the entire week. If you have access to the internet, any updates or changes to the menu will be automatically updated. The app also has a handy "favorites" feature that remembers the most frequently accessed cafeterias and removes those you no longer visit.

Mensa is a useful app for students or anyone who wants to keep an eye on their campus cafeteria's menu. The app provides accurate and up-to-date information on the menu and the cafeterias, and the "favorites" feature saves you time by allowing you to quickly access the cafeterias you visit most frequently. If you find any errors or your cafeteria's menu is not available, you can contact the developer via email at to provide feedback.
