MinMaxCal
A minimal calendar and reminder interface (Min) which pulls you out of flow and into meetings with a full-screen takeover and one-click join (Max).
Free and open source
Apple silicon · macOS 26+
I used the meeting reminder app In Your Face for a few years and was paying £20 for it. I decided to build a replacement to address a few annoying edge cases such as combining identical events (Fantastical-style). Within about two hours it was just as good for my usage. Within two weeks, it was better in every way. That’s how MinMaxCal started.
Stop coding, join meeting
Most of the time MinMaxCal shows only the next event or reminder and a countdown in the menu bar. Click for today’s and tomorrow’s agenda. When an accepted event or reminder is due, the alert fills every display, including full-screen apps.
Join Zoom, Teams, Meet or Jitsi calls from the alert, or press Return to join a call or complete a reminder. Dismiss the alert or snooze a reminder if you need more time.
Optionally, record a transcript and keep track of how much time you’ve spent talking in the meeting (I talk too much).
Zero required configuration
MinMaxCal uses the calendars and reminder lists you already have in macOS. Choose which ones to show, with duplicate meetings combined and overdue reminders kept visible until completed. Your Mac’s accounts handle syncing, so there’s no extra account to create.
Optionally copy events between calendars, keeping the details or showing only Busy or Travel to replace tools like Reclaim.ai if that’s all you use them for.
There’s also a minimal iOS and watchOS app providing the same simple view of your calendars and reminders on your phone or watch.
