CalWidget

A native macOS widget that shows a full month view of your Google Calendar, right in Notification Center or on your desktop. It reads Google Calendar directly, so it doesn't depend on syncing through Apple Calendar.

Features

How it works

  1. Open the app and sign in with your Google account.
  2. Add the widget from Edit Widgets in Notification Center or on the desktop.
  3. The widget refreshes in the background and shows the current month.

The app asks only for read-only access to your calendar. It can't create, edit, or delete events.

This data is used only to display your calendar on your own Mac. It goes straight from Google to your Mac and is never sent to us or anyone else. It isn't used for advertising or to train AI models. The full details are in the Privacy Policy.

Setup

No setup beyond signing in. Click Sign in with Google, allow read-only access to your calendar, and add the widget. See the Support page for details.
