Calendar App Chrome Extension: Review & How to Use (2026)

Calendar App Chrome extension

Calendar App (listed on the store as "App for Google Calendar") is a lightweight launcher: click the toolbar icon and Google Calendar opens instantly, no bookmarks bar or typing a URL needed. It's best for people who check their calendar often and want one less click. The catch: it doesn't add scheduling features of its own, it just opens the existing Google Calendar site.

What Calendar App does

Calendar App is a browser extension that gives you quick access to Google Calendar. Instead of typing the URL or digging through bookmarks, you click the toolbar icon and Google Calendar opens right away. It's a convenience shortcut rather than a calendar replacement, so all your events, reminders, and settings still live in your regular Google Calendar account.

Calendar App free vs paid

The extension itself is free to install and use, with no separate premium tier listed on the store. Any paid features you might use, like Google Workspace calendar add-ons, come from Google's own products, not from this extension. It exists purely to save you a step in reaching your calendar.

Is Calendar App safe?

Because it just opens a Google Calendar page, its own permission footprint is minimal compared to extensions that read page content. Review the permissions shown on the Chrome Web Store listing before installing, and only grant access you're comfortable with, as you would with any browser extension.
