About UMST

UMST places a calendar on your desktop, beneath your windows, showing the next two weeks. It combines every calendar on your Mac with Apple Reminders, school systems (Canvas, Blackboard, Brightspace, Moodle and Schoology) and task apps (Todoist, Asana and Trello), and a menu bar item adds to-dos in two keystrokes. It suits students and anyone juggling school, work and personal calendars in one view. It connects through calendar feed links and API tokens, which the README says are kept in the macOS Keychain, and it has no accounts or analytics.

It needs macOS 14 or later on Apple silicon or Intel. The README says the app is not yet notarized by Apple, so the first launch is blocked until you choose Open Anyway in System Settings under Privacy & Security. The one-line installer also installs Show Desktop, a separate MIT-licensed app by another developer, and the README offers a plain zip download as well.
