10 Best Calendar Apps for Mac of 2026

Notion Calendar is the most practical upgrade for a Mac user who lives in Google Calendar and does not want to pay. The vendor lists sync with Google Calendar accounts, Outlook calendars and Apple iCloud-synced calendars, so work and personal schedules sit in one view, and it can auto-block busy slots across every connected calendar to prevent double bookings. Built-in scheduling lets you send your availability and a booking link without a separate tool, and the menu bar lets you join the next meeting without opening the full window. Google Meet is available by default with Google accounts, Zoom meetings can be created inside the app, and a custom link covers other services. If you use Notion, deadlines and timelines from your databases appear beside events and can be moved by dragging. The limits are real: there are fewer views than in the paid Mac apps, and Notion says importing Google Calendar events into a Notion database is not yet possible.

Fantastical is the best known third-party calendar for the Mac and earns that reputation through its parser. Type a phrase such as lunch on Friday at 1pm, or a repeat like the third Thursday of every month, and it builds the event with alerts and the right calendar; start the sentence with remind me to and it creates a task. The free version already includes the full window with day, week, month, quarter and year views, a mini window on a keyboard shortcut, Todoist and Google Tasks support and a three day weather forecast. Flexibits Premium adds Openings for sharing availability, Proposals for meeting polls, video call links for Zoom, Google Meet, Webex and Teams, calendar sets that switch by location, templates, invitee availability lookups and push updates for Google and Exchange. It connects iCloud, Google, Exchange and Office 365. The trade-off is cost: at $56.99 a year, Premium is a real expense, and the free version is mostly a polished viewer.

BusyCal is the calendar for people who want to shape every view. The vendor describes week views of 2 to 31 days, month views of 1 to 12 weeks, a year view that can work as a heat map of your busiest months, and a sortable list view with duration totals. Tasks sit directly on the calendar and carry forward until done, with sync to Apple Reminders, Google Tasks, Todoist and Microsoft To Do. Account support is the widest in this list: iCloud, Google Calendar, Microsoft 365, Outlook.com, Exchange, Yahoo, Fastmail and any CalDAV server, with push updates where supported. Meeting tools include availability checks on Google and Microsoft 365, join buttons for Zoom, Teams, Meet, Webex and GoTo, and a Bookings page. A menu bar app, color tags with time tracking and smart filters round it out. It is free for everyday calendaring with a 14-day trial of the full app; the cost of the depth is a busier interface.

Calendar 366 is a fast, native Mac calendar that doubles as a menu bar app, so you can check the month or add an event without opening a full window. The App Store listing describes 13 views, including year, month, agenda and week layouts of 3 to 14 days, and natural language entry for events. Tasks live inside the calendar with priorities, location alerts and filters. It connects to the Mac's own calendars, iCloud, Google Calendar and Google Tasks, Outlook and Microsoft 365, Todoist, Fastmail and CalDAV, and it can create Zoom, Google Meet and Teams meetings. There are 20 interactive desktop widgets, calendar sets, Shortcuts support, a URL scheme and an MCP integration for AI assistants. Pricing is lower than Fantastical, with Pro at $19.99 a year or a $49.99 one-time purchase. It has far fewer reviews than the bigger names, and a few reviewers mention bugs, so try it before you pay.

Apple Calendar is the baseline every other app on this list has to beat, and for many people it is enough. Apple's user guide explains how to add calendars from internet accounts such as iCloud, Google or another CalDAV account so that all your events appear in one place. You can create separate color-coded calendars, share calendars, send and receive invitations, and show scheduled reminders beside events so your to-do list and meetings live together. It also displays holidays, birthdays and Chinese, Hebrew or Islamic lunar calendars, and Siri Suggestions can surface events found in other apps. Because it is part of macOS, it syncs with an iPhone or iPad through iCloud with no extra account. What it lacks is speed for heavy users: there is no booking page, no meeting polls, fewer view options and less control over Google features than Fantastical, BusyCal or Notion Calendar. Several menu bar apps here, such as Itsycal and Dato, read its accounts and add to it.

Calendars by Readdle brings a popular iPhone calendar to the Mac with a focus on planning, not just viewing. The App Store listing describes connecting multiple calendars from Google, iCloud or Outlook along with Google Tasks and Reminders, then dragging tasks onto the calendar to give them a time slot. Templates let you schedule recurring personal blocks such as workouts in seconds, and events can be created with natural language. Day, week, month and list views, color coding, weather, interesting calendars and integrations with Zoom, Meet and GoToMeeting cover the core needs. Readdle says users without a subscription can use the basic version on Mac, while PRO subscribers on iPhone get the Mac version and its Planner feature at no extra cost. PRO costs $3.99 a month or $19.99 a year in the US store. It is less configurable than BusyCal and connects fewer account types, but it is well priced for people who already use Readdle apps.

Outlook for Mac makes the most sense when your employer runs Microsoft 365 or Exchange, but it is also free with personal email accounts. Microsoft's App Store listing says it works with Microsoft 365, Outlook.com, Gmail, Yahoo, iCloud, IMAP and POP accounts, so you can keep a work Exchange calendar and a personal Google calendar in one app. The integrated calendar lets you plan meetings, check availability, track RSVPs and share your calendar, and the My Day panel shows your agenda and a two-week view beside the inbox. You can set meetings to be virtual by default and to start or end early. A premium subscription removes ads; Microsoft lists Microsoft 365 Basic at $19.99 a year on its US page. The downside for calendar-first users is that Outlook is a mail client with a calendar attached, and it lacks natural language entry, tasks on the calendar and booking pages found in the dedicated apps.

Dato is a menu bar calendar built for people whose days are full of video meetings. It shows a local clock, the date, multiple world clocks and your upcoming events in the menu bar, and a click opens a calendar with event indicators and week numbers. Its signature feature is a full screen notification when a meeting starts, with a join button that recognizes Zoom, Google Meet, Teams and dozens of other services, plus a global shortcut to join the next call. Dato supports every calendar service macOS supports, so Google calendars added to the Mac appear automatically, and Google events can open straight in Google Calendar on the web. It also deduplicates identical events from different calendars, shows reminders and can create events. The developer sells it as a one-time $18 purchase with free upgrades and says it will never be subscription-based. It is a companion, not a replacement, and menus and settings are English only.

Itsycal is a small free utility rather than a full calendar, and that is its appeal. It sits in the Mac menu bar and opens a month view with your upcoming events, drawing them from the Mac Calendar app, so any Google account you have added to macOS shows up without a separate sign-in. The developer lists event creation and display, viewing and completing Reminders, joining virtual meetings, ISO week numbers and an optional hourly beep. Navigation is quick: there is a configurable shortcut to open it, keyboard controls including Vim motions, jumping to a specific date and a URL scheme. You can show up to two months at a time, change font sizes, use dark mode and have it replace the system clock. The developer says the apps are free and accepts donations. It will not replace a main calendar for heavy schedulers, but it pairs well with Apple Calendar, Notion Calendar or Google Calendar in a browser.

Morgen is the choice for people who want their calendar to plan the day for them. Its pricing page lists time blocking supported by an AI Planner, unlimited calendar and task integrations, calendar automations, a booking page and scheduling links, all in one plan. It runs as an app on macOS, Windows, Linux and mobile and in the browser, which helps people who move between a Mac at home and a Windows or Linux machine at work. The vendor says the service is Swiss-hosted and GDPR compliant. There is a 14-day free trial with full access and no credit card, and a 30-day money-back guarantee. After that it costs $15 a month billed yearly or $30 billed monthly, with team plans from $10 per seat billed yearly. That price is far above every other app here, so it only makes sense if you will use the AI planner and task integrations every day rather than just viewing Google events.
