Home » The Best Online Shared Calendar Tools

Collaborating with contacts online has never been easier, but the process of finding the best possible shared calendar for a group can be intimidating. There are dozens of possibilities, each with their own pros and cons. Where do you even start?

Your group needs tools to help you hit deadlines, and you shouldn’t be all alone in finding the right choice for you. Hopefully, this guide helps provide a good overview. We’ve collected a few of the absolute best online shared agenda tools, along with some tips and info for getting the most out of them.

Google Calendar

The biggest of them all, this is almost certainly the most used and most well-known online agenda sharing tool around the world. With a clean, simple design, it may be the obvious choice for basic scheduling needs. Here are a few of the options Google boasts:

  • Multiple custom color coding options.
  • Can sync from the cloud with many other programs, including professional to-do-list apps.
  • Platform agnostic – available from any phone or web browser.
  • Completely free – requires making a Gmail account.

Apple iCloud

While not quite as massively common as Google’s option, iCloud (also known as iCal) remains a popular shared calendar with iPhone and Mac users. In fact, that’s the one downside holding it back: if you’re not on iOS, it’s probably not worth the trouble. Technically you can access iCloud from Android and other platforms, but it’s just not the best experience. Nevertheless, Apple has some benefits of its own:

  • Seamlessly integrates with other Apple and iOS software, like Maps and Weather.
  • Daily, weekly, and monthly views to help you follow along with your day or long-term plans.
  • Ability to book appointments with voice commands through Siri.
  • Completely free – requires making an Apple account.

Outlook Calendar

This one has a similar problem to Apple: unless you and your group are operating primarily from Windows machines, it’s probably not the ideal choice. That said, Microsoft has built a lot of great features to appeal to businesses. It may not be the best app for organizing to-do lists, but here are some reasons to check it out:

  • Full integrations with your emails via your inbox.
  • Higher level of security.
  • More project management options, such as the ability for a manager to track scheduling for an employee.
  • $6.99 per month per user – includes access to Microsoft’s full Office suite of tools.


While other digital planners are designed for individuals but include the ability to share with a group, TeamUp is designed for groups from the ground up. It may not be for everyone, but it includes a lot of extra power, making it one of the best organization online tools. Here are some of the functionality that helps set it apart:

  • Different levels of access for different people.
  • Extremely customizable, with multiple layers of color-coding and ability to view event details at any point.
  • Ability to build sub-calendars and assign a single event to multiple groups.
  • Ability to share specific events without needing to publish your full schedule to the public.
  • Pricing ranges from free for basic access to as high as $80 a month for large companies.
