Itsycal vs Mou Sugu: which menu bar calendar fits you?
Short version: they solve different problems. Itsycal puts a mini month calendar in your menu bar; Mou Sugu puts a live countdown to your next meeting there.
Itsycal has earned its place as a Mac classic: a tiny, free, open-source calendar that drops a month view into the menu bar, lists your events, lets you create new ones, and stays impressively light. If what you miss on macOS is a calendar you can glance at, Itsycal remains a lovely answer.
Mou Sugu starts from a different question: not “what day is it?” but
“how long until I have to be somewhere?”. The menu bar shows
in 12m: Standup, updates every minute, and puts a Join button for Zoom, Google
Meet, Microsoft Teams, and Webex one click away.

Choose Itsycal if…
- You want a month calendar you can open from the menu bar.
- You create quick events all day and want to do it from the bar.
- You run an older version of macOS.
Choose Mou Sugu if…
- Your day is meetings, and the thing you check is how long until the next one.
- You want the Join button where your eyes already are — no popover required.
- You prefer an app that reads your calendar and touches nothing.
They also coexist happily: plenty of people run a mini calendar and a meeting countdown side by side. Both are free, so trying costs nothing.
