10 Best Calendar Apps of 2026

Morgen fits the brief of this list better than any other product we compared because it covers all three jobs in one subscription. It pulls Google Calendar, Outlook, Microsoft 365, iCloud and Fastmail calendars into one view, then adds tasks from tools such as Notion, Todoist, Linear, ClickUp and Microsoft To-Do so you can drag them onto the calendar as time blocks. The AI Planner proposes a plan for the day, but Morgen's own comparison stresses that you stay in control rather than having tasks moved automatically. A Booking Page and Scheduling Links are included, and calendar automations handle repetitive edits. Apps run on Windows, macOS, Linux, iOS, Android and the web. Morgen AG says data is stored in Switzerland or the EU. The trade-off is price: there is no free plan, Pro costs $15 per month billed yearly or $30 monthly, and the team plan needs at least 2 seats.

Notion Calendar is the strongest free answer to the several calendars problem. It connects Google Calendar accounts, Outlook Calendars and Apple iCloud-synced calendars, then auto-blocks busy slots across all of them, so a personal appointment no longer leaves your work calendar looking open. A built-in scheduling link lets you send availability without a separate booking app, and the menu bar lets you join meetings without opening the main window. The Notion tie-in is the distinguishing feature: deadlines and project timelines from Notion databases appear beside your events, and you can drag database items to new dates from the calendar. There are desktop apps for macOS and Windows and mobile apps with widgets for iOS and Android, in 12 languages. What it lacks is planning help: there is no AI time blocking, and Notion says Google Calendar events cannot yet be imported into a Notion database.

Reclaim.ai is not a calendar app you open instead of Google Calendar or Outlook; it works inside the calendar you already use and changes what lands on it. Focus Time takes a weekly goal and defends hours around your meetings, Habits slot recurring routines into the best open window, and Buffer Time adds breaks after video calls. For people with several accounts, Calendar Sync copies events between calendars so each one shows your real availability, and Scheduling Links let others book time based on priority settings. The free Lite plan is unusually complete for one person, with 1 Calendar Sync, 1 Scheduling Link and a 1 week automated scheduling range. Starter at $10 per seat per month raises that to 3 syncs, 3 links and an 8 week range, and Business at $15 makes syncs and links unlimited. Reclaim lists only Google Calendar and Outlook support, so iCloud users need another tool.

Fantastical is the calendar app for people who live on Apple hardware and want more control than Apple Calendar offers. It adds iCloud, Google and Exchange accounts directly and shows tasks from iCloud Reminders, Todoist and Google Tasks next to events. The parser turns typed sentences into events, repeating rules and alerts. For several calendars, calendar sets switch groups of calendars on or off with a click or automatically when you arrive at or leave a place, and Premium can combine duplicate events that appear on more than one calendar. Scheduling sits in Premium too: Openings let others book based on your availability, Proposals run meeting polls, and Zoom, Google Meet, Webex and Teams links can be added to events. Flexibits Premium costs $6.99 a month or $56.99 a year on the US App Store, with a 14 day trial. There is no automatic time blocking, so planning stays manual.

Google Calendar is the default for many professionals, and for good reason when most of your calendars are already Google accounts. It is free, runs on the web and on iPhone, iPad, Apple Watch and Android, and includes appointment schedules, which create a booking page others can use to grab time with you. Google's help center documents useful controls: appointment duration, weekly availability, a scheduling window, a minimum lead time that defaults to 4 hours, adjusted availability for holidays, buffer time and a cap on bookings per day. The limits matter for this list. You can only create an appointment schedule on a computer, not in the mobile apps, and Google says some appointment schedule features require an eligible Google Workspace or Google One subscription. There is also no planning layer that turns tasks into time blocks, which is why many users pair it with Reclaim.ai or Morgen.

Motion goes furthest of any product here in handing your calendar to software. Its AI Calendar takes your projects and tasks, plans them by deadline, duration and priority, and recalculates the day and week when a meeting runs long or something urgent arrives. It also warns when you have scheduled more than you can handle, which is useful for professionals whose calendars fill with meetings from several sources. Motion includes booking links and lets you embed your calendar on a website so prospects can book your preferred slots. The catch is scope and cost: Motion is now a broader AI work platform with projects, docs, notes and chat, Pro AI costs $19 per seat per month billed annually with 7,500 AI credits, and there is no free plan, only a trial. If you want suggestions rather than an engine that moves things for you, Morgen or Reclaim.ai are lighter choices.

Vimcal is built for people whose job is mostly meetings. Its FAQ names founders, executives and VCs as the audience, and the product reflects that: Google Calendar and Outlook show in one unified view, availability can be dragged and copied into an email, time zones convert automatically and duplicate events merge. The paid iOS & Desktop plan adds unlimited personal booking links, polls for group scheduling, desktop apps for Mac and PC, a Mac menu bar app and team scheduling features. A separate Vimcal EA tier serves executive assistants with 5 simultaneous time zones, auto-created calendar holds, weekly calendar metrics and per-executive preferences. Vimcal lists ISO 27001, SOC 2 Type II and HIPAA for security reviews. The price is the main drawback: the desktop plan costs $300 a year or $35 monthly, and there is no task list or time blocking engine, so it suits meeting-heavy roles more than planners.

Outlook is where many corporate calendars already live, and Microsoft pitches it as a place to stay on top of multiple accounts with email, calendars and contacts together. The free Outlook account gives you email and calendar on web, desktop and mobile with a 15 GB mailbox, Outlook for Windows is included with Windows, and the macOS app is free for personal use. Microsoft 365 Basic at $19.99 a year removes ads and raises the mailbox to 100 GB, and higher plans add Copilot for summarizing threads and drafting replies. For this list, Outlook's strength is that it handles work Exchange calendars natively and sits right next to the inbox where meeting requests arrive. Its weaknesses are planning and booking: the consumer page we checked lists no booking links and there is no time blocking engine, so professionals often add Reclaim.ai, Morgen or Vimcal on top.

Akiflow approaches the calendar from the task side. It collects tasks into one inbox, then lets you drag them onto a calendar that syncs with Google Calendar and Outlook Calendar, which makes it a time blocking tool first and a calendar second. The pricing page lists a daily planning ritual, recurring tasks, priorities, labels, availability sharing, productivity analytics, Zapier and IFTTT automations, emails into tasks, 2-way sync, and the Aki AI assistant with an MCP Connector. Desktop and mobile apps are included. For someone juggling work from many tools, that central inbox is the draw: tasks from different apps land in one list and get a slot in the week. The costs are clear. Pro is $19 per month billed yearly or $34 billed monthly, there is no free plan, and the trial is 7 days. iCloud calendars are not listed among the synced providers.

Apple Calendar is the baseline every iPhone and Mac user already has. Its App Store description is direct about the multi-account case: connect accounts from iCloud, Exchange, Google and others, color code multiple calendars and view everything together in List, Day, Week or Month views. Reminders from the Reminders app sit beside meetings, iCloud calendars can be shared with family or colleagues who can add and edit events, and location-based alerts tell you when it is time to leave. Holiday, birthday and subscribed calendars round it out. For the professionals this list targets, the gaps are significant. There is no booking link or appointment page, no way to propose times to outsiders, and no planning tools that turn tasks into time blocks. It is the right choice if you mainly need to see every calendar on Apple hardware for free, and the natural upgrade path is Fantastical.
