InstaCal for Mac — Menu Bar and Full Calendar

One app, every scale

A glance, a panel or the whole calendar.

InstaCal gives each job the right amount of space, from the strip at the top of the screen to a planning window with three working panes.

The InstaCal panel open in the macOS menu bar: a July month grid above an agenda showing today's events with a live countdown, a Zoom link, due reminders, and weather in each day header — **Menu bar panel** — Month, agenda, reminders, weather and Join in one fast surface.

InstaCal's full calendar window in dark mode: the agenda sidebar, a month grid with Day, Week, Month, Quarter, Year and List view options, and an event's details open in the right-hand inspector — **Full calendar** — Six views with the agenda and event inspector beside them.

InstaCal's event editor showing calendar selection, start and end times, duration chips, location, alert, invitees, notes, and repeat and availability options — **Complete editor** — Times, attendees, alerts, repeat, availability and attachments.

FAQ

Questions about InstaCal for Mac

What does InstaCal require?

macOS 14 Sonoma or later, on Apple silicon or Intel. InstaCal is a native Swift app — not a web wrapper — so the panel opens instantly and uses very little power.

Is InstaCal only a menu bar calendar?

No. The menu bar is the fastest surface, and the same Mac app includes a full window with Day, Week, Month, Quarter, Year and List views, an agenda sidebar and event inspector.

Does it work with Google and Microsoft 365?

Yes. Use calendars already available through Apple Calendar, or connect Google and Microsoft directly for incremental sync and richer invitation actions.

Does InstaCal collect any data?

No. InstaCal contains no analytics and no tracking. Your Google and Microsoft tokens live in Apple's Keychain, and your events sync directly between your device and your calendar provider — there is no server of ours for your data to visit.

How much does InstaCal cost?

InstaCal is $29 once. One App Store purchase includes the Mac, iPhone, iPad and Apple Watch apps. There is no subscription, separate mobile purchase, Pro tier, InstaCal account or in-app purchase.
