There’s no shortage of Mac calendar apps out there, from the default option that comes pre-installed with the machine to other free alternatives to paid but full-featured third-party apps.

The problem is that you really need just one best free calendar app for Mac. Not sure which one you should choose? I did some research and put together a short list of just five calendar apps that I believe cover most use cases and everyday needs — without overwhelming you with options. So let’s dive in!

Just 5 calendar apps to cover almost every use case and workflow

Apple Calendar — the best free calendar app for Apple users

For the first contender to become the best free calendar app for Mac, why not consider the calendar app you already have pre-installed?

Mac Calendar (iCloud Calendar) app is simple and easy to use. The calendar itself takes up most of the interface. You can easily switch between different views using the tabs in the top bar.

Creating new events is easy, too: just double-click any time of day and fill in any of the fields. If a similar event has already been created, you can choose an automatic suggestion. Apple Maps will also automatically suggest a location for your event. You can also invite anyone to your event via email, even if they don't use Apple Calendar app. For the event itself, you can choose from a variety of custom-designed and color-coded calendars.

You can create as many local calendars as you want, and they all sync with iCloud. It's also possible to add calendars from Exchange, Google, Yahoo, or AOL accounts. That's handy if you need to balance work and personal calendars.

Pros
  • Simple and easy to use
  • Ability to manage multiple calendars at once
  • Event invitations with response tracking
  • Time zone selection
  • Daily, weekly, and monthly view
Cons
  • Lacks some advanced features
  • It can be difficult to share calendar with people who don't use Apple devices
Supported platforms
  • macOS
  • iOS
  • ipadOS
  • watchOS
  • web (via icloud.com)

Free with iCloud.


BusyCal — the most flexible calendar app for Mac

BusyCal is all about flexibility, and you can see that when you explore the calendar's features and settings. You'll find options to change colors, fonts, and customize the display panel. You can even add a second time zone to the sidebar — a handy feature for those who either travel frequently or work with overseas teams.

Surprisingly, what makes BusyCal different from Apple's calendar isn't immediately apparent. When you dig a little deeper, you start to notice the differences. There are interesting features like displaying weather forecasts and moon cycles in the weekly and monthly views. BusyCal also allows you to view alternative calendars such as Hebrew, Islamic, or Chinese dates alongside the traditional Gregorian.

The right side of the app displays your to-do list, which is pulled from apps like Reminders or Todoist. If you don't use those apps, you can configure it to show details about the current event, or even stack your to-do items and details on top of each other. You can also add task due dates directly to the calendar.

BusyCal calendar

BusyCal offers five main views — daily, weekly, monthly, yearly, and a list view. There's also a handy menu bar icon to quickly browse your appointments, and the availability panel lets you quickly find an open slot in your schedule.

The app can sync with iCloud as well as your calendars from Google, Yahoo, Fruux, Fastmail, Office 365, Outlook, CalDAV, and Exchange. I also love the ability to sync with Todoist, Zoom, GoTo Meeting, and Webex. But different people prefer different features. Here's what one BusyCal user from Reddit likes about the app: "Compared to Calendar.app. I just like the widgets and views better. And in terms of features, I like the menu bar item on Mac — but the big one is travel time. I'm really bad when it comes to time, so I love that, on events that has a location, you can also set where you'll travel from, and the means of transportation. (I switch between transit and car.) Then you can set an alarm for things like "15 minutes before I need to leave", and it will adjust."

Pros
  • Integration with many cloud services
  • Integration with conferencing platforms such as Zoom and Webex
  • Daily checklists in the sidebar on the right side of the app
  • Task synchronization with the Reminders app for Mac 10.14
  • Many customizable options, including layout and appearance
  • Time zone selection
  • Weather feature
  • Widgets for every need
  • Daily, weekly, monthly, yearly, and list view
Cons
  • Exclusive support for iOS and macOS only.
Supported platforms
  • macOS
  • iOS

Microsoft Outlook calendar — Mac calendar for Microsoft enthusiasts and cross-platform syncing

Microsoft's Outlook provides a departure from the typical Mac approach of having a separate app for each function. Instead, it combines various features such as email, contacts, to-dos, and the calendar, potentially making it a suitable choice for those in conjunction with work or simply seeking a multifaceted tool.

Appointment views in Outlook come in four formats: Day, Work Week, Week, and Month. The Work Week view, which is unique to Outlook among the calendar apps discussed here, showcases its work-centric design. Integrated features such as a three-day forecast toolbar are examples of additional functionality. Email and contact integration underscore the focus on collaborative tasks, and meeting templates add efficiency, especially if you frequently organize similar meetings.

The process of adding appointments in Outlook lacks the smart entry feature of its competitors, which may seem clunky. However, appointments created in a separate window can be quickly scheduled using the tab key. To further its work-oriented appeal, there's a scheduling wizard that lets you coordinate with multiple people to find a mutually convenient time.

On top of that, Outlook supports a wide range of accounts, including Microsoft 365, Outlook.com, Google, Yahoo, iCloud, POP, and IMAP, although Exchange support requires reverting to a previous version of Outlook. One notable exception is that iCloud calendars not associated with an iCloud email address are not currently supported. While this may seem odd for a Mac calendar app, Outlook has superior adaptability when it comes to cross-platform integration.

MS Outlook for Mac

In general, Outlook may not be the immediate app you'd expect to find in a macOS calendar conversation, but it's still worth considering, especially for those who already subscribed to Office. While it lacks macOS-specific features and lacks the native Apple feel of other apps in this category, Outlook covers all the bases of a versatile calendar.

Pros
  • Integration with the Microsoft Ecosystem
  • Numerous features, such as conditional formatting, customizable views, and advanced categorization
  • Supports complex scheduling, resource management, and meeting invitations
  • Offline accessibility
  • Supports a wide range of accounts
  • Day, Week, Work Week, and Month view
  • Customizable appearance
Cons
  • Steep learning curve
  • One-app-many-functions design 
Supported platforms
  • macOS
  • iOS
  • ipadOS
  • Windows
  • Android 
Price

Starting at $6.99 per user per month as part of Microsoft 365 Personal or $6 per user per month as part of Microsoft 365 Business Basic.
