In this blog post, I’m breaking down the twenty best Google Chrome extensions for scheduling meetings, blocking time for upcoming tasks, and using Google Calendar to make the best use of your valuable time.

Well, we hear you.
That’s why we analyzed hundreds of extensions and found the 20 best that are most relevant to busy startup founders and executives.
And by the time you read our list of favorites, you’ll know exactly which Google Calendar extensions to add to Chrome to personalize your Calendar experience.
Let’s slide into it!
To be included in our list of the best Google Calendar extensions, extensions must be currently available (either in the Chrome Web Store or on a website that is safe to visit), not be flagged as a potentially harmful extension, and have largely positive user reviews.
Disclaimer: Please note that I was provided with compensation in return for my honest review. This is not an exhaustive list of all the different extensions out there as with 4 million Chrome extensions downloaded daily, that wouldn’t be practical. Every attempt has been made to provide accurate and up-to-date information as of the time of publication.

“How have I been doing anything without this…? It is seriously so easy to use, far better than any other ‘google calendar’ extensions… I can type in the date and time and it will recognize that easily. It is so fast to put reminders in and events without having to mess around with changing the date or time like my other extensions needed me to do. Very smooth experience, and I appreciate that very much!”
Clockwise is an intelligent calendar assistant that uses AI to create uninterrupted blocks of time in your schedule to enable more deep work time and eliminate the need for context switching. It also resolves double bookings, has simple and sleek integrations with Slack, Google Calendar, and web applications, and is highly customizable.
This extension is rated 4.7 out of 5 with 154 reviews and 100,000+ users.
Users praise the easy onboarding and seamless integrations. Yet other users complain that it doesn’t work outside their company with external users. There are also some complaints that it works fine initially but then starts giving “connection error” messages even when users have solid internet access.
TechCrunch called Clockwise “one of the more interesting offerings” in the time management software and daily planner space.
You want to use Clockwise!! As a manager, I love that it creates more focus time for people on my team and minimizes the time between meetings where you really can’t get much done because of context switching! I also like the idea that it helps solve conflicts (like the perfect assistant). My recommendation, get your entire team into Clockwise and make sure they configure their meeting hours to see the advantages.

Meetric works directly with your Google Calendar or Google Meet and allows you to take notes without switching windows. Easily capture meeting minutes, take notes, and assign tasks to yourself and others in the meeting. This extension also has a built-in timer to help you keep meetings on track.
This extension is rated 4.8 out of 5 with 57 reviews and 2,000+ users.
You can use Meetric in any web-based video conferencing tool, like Google Meet or Microsoft Teams; Collaborate in real-time on the agenda & the notes with other guests. When you have reoccurring meetings, your meeting notes from prior meetings are pulled in automatically. The older meeting notes are dated and get pushed down each time a new meeting occurs so you can reference and pull from those as well. Some users complain it is difficult to find older notes.
We use this tech and it solves a real problem around accountability during and after meetings. Would recommend anyone who has daily meetings to check it out.
Well done guys!!!

TeamCal allows you to add team scheduling and planning functionalities to your Google Calendar and displays all your calendars at once using a horizontal timeline view. You can use TeamCal to schedule and to identify gaps and overbooking of your workers. There is a 30-day free trial and after that pricing starts at $29.00 per user, per month. They do not have a free version. This extension is perfect for managing employee scheduling, staff rotations, on-call duty time, and team vacations & leaves. It has Mobile Access, Resource Management, Schedule Distribution, and Shift Swapping.
This extension is rated 4.1 out of 5 with 10 reviews and 2,000+ users.
TeamCal gives you the ability to see your whole team’s Google calendars and what is on the books for each of them and the ability to catch double bookings. Some users complain the different format can be confusing at times and that it is difficult and time consuming to arrange the calendars within the TeamCal view without drag-and-drop functionality. A Shopify review says, “If you’re managing a team, TeamCal may be the tool you need.”
It’s been great since day one. The biggest benefit by far is the ability to catch double booking and alert staffing about said issue, ensuring there are enough team members to support an event. Hands down, the ability to see my whole team’s (over 60 reports) specific google calendars and what is on the books for each of them. Personally, my favorite view is “the week at a glance” This allows me to identify potential conflicts at a broader scale. I also love how customizable you can make your team view, for example, I have my FT reports listed first and then my PT reports below them, regardless of alphabetizing , and on top of that, I can color code to specific areas of expertise.

You can set a range of working hours during the day that fits your schedule and take away the unnecessary white space for the times you’re out of the office or sleeping. Some users complain that you can’t hide night hours.
It did exactly what I needed. I work during the day, so it was nice to eliminate anything between 1am and 6am (you can customize that). Great little app!

I’m glad someone picked up the project since I use this extension several times a day. Love the minimalistic view, the option to see how long it is until the next meeting at a glance, and the option to join meetings without opening google calendar. Would recommend the extension to anyone!

The colors are only available on the web version of Google Calendar and will only stay consistent on one browser on a computer unless Google Chrome sync is enabled, then the colors will be attached to your Google Chrome profile. Some users complain the colors do not stay once selected and that color changes can’t be applied to all-day events or events that you didn’t create.

Appointment Reminder is amazing! We have been maintaining a Google calendar for quite some time and manually texting people. This has saved us so much time and has improved our “SHOW” rate and therefore our income. A larger than normal portion of our customers need reminders since their appointments are set so far in advance. This is sooo worth the money! It was very easy to set up and online support is very helpful if you have any questions.
