A newly launched Mac app called Superpowered aims to make it easier to stay on top of all your Zoom calls and Google Meets, without having to scramble to find the meeting link in your inbox or calendar app at the last minute. Instead of relying on calendar reminders, Superpowered offers a notification inbox for the Mac menu bar that alerts you to online meetings just before they start, which you can then join with a click of a button.

To use Superpowered, you first download the app then authorize it to access to your Google Calendar. The app currently works with any Google account, including G Suite, as well as your subscribed calendars.
