What InstaCal is
InstaCal is a native calendar for Mac, iPhone, iPad and Apple Watch. On Mac, its fastest surface is the menu bar panel: click the date or press your global shortcut to see the month, agenda, reminders and invitations without switching away from your work. A full six-view calendar window is included for longer planning sessions.
On iPhone and iPad, InstaCal is a complete calendar rather than a companion. It includes Agenda, Day, Week, Month, Quarter and Year views, event and reminder editors, invitations, weather, widgets and meeting tools. Apple Watch focuses on Now, Next and Later.
Purchase and requirements
One $29 App Store purchase includes every platform. There is no subscription, separate mobile unlock, InstaCal account or paid feature tier.
| Device | Requirement |
|---|---|
| Mac | macOS 14 Sonoma or later |
| iPhone and iPad | iOS or iPadOS 18 or later |
| Apple Watch | watchOS 11 or later |
Where your calendars come from
InstaCal can read the calendars already available through Apple Calendar and Reminders. You can also connect Google and Microsoft 365 directly for faster incremental sync and provider-specific features such as invitation replies.
Note: InstaCal does not replace your calendar provider. Events remain with Apple, Google or Microsoft and continue syncing through those accounts.
