Vendors can pay for more visibility on this website, for example a higher place in a ranking or more room on a page. Commercial relationships can also affect which products we feature and how prominently. Every vendor link is marked the same, whatever the arrangement behind it. The largest vendors in calendar apps
cannot hold places 1 to 3. Places 1 to 3 go to challengers, vendors outside the best-known brands in a category,

The 13 tools, reviewed
#1 Morgen
Calendar and task planner across all your accounts · Switzerland · morgen.so
multi-account time blocking Swiss
Morgen answers the question most multi-account users ask first: can one window hold work, personal and client calendars without a browser tab for each? It connects Google, Outlook, iCloud and Fastmail, pulls tasks from Todoist, Linear and Notion beside the events, and offers an AI planner that is optional, which is the right default.
- Pricing: Per seat / month. Pro from $15 per month billed yearly and Team at $10 per seat per month billed yearly with a two-seat minimum, both starting with a 14-day free trial. Free plan: free trial.
- Best for: Multi-account professionals on any desktop
- Strengths: Google, Outlook and iCloud calendars; AI daily planner; Task integrations (Notion, Todoist, Linear, ClickUp).
Where it falls short
There is no permanent free plan, so the product is a subscription from day two. Because Morgen reads accounts held at Google or Microsoft, those providers still store your events, which limits the privacy claim.
Wrong for
Anyone who wants a no-cost calendar or an encrypted schedule that no third party can read.

#2 Proton Calendar
End-to-end encrypted calendar from the Proton ecosystem · Switzerland · proton.me
encrypted Swiss privacy
Proton Calendar encrypts event titles, descriptions, locations and guest lists so that Proton cannot read them, and it extends zero-knowledge encryption to events received from people on other calendars. That is the point of choosing it, and few rivals match it. It is free for three calendars, supports recurring events, invitations, import and export, and now lists appointment scheduling.
- Pricing: Free + paid plans. Free plan with three calendars. Free plan: free plan.
- Best for: Privacy-focused individuals and small teams
- Strengths: End-to-end encrypted events; Zero-knowledge encryption for outside invitations; Appointment scheduling.
Where it falls short
Link sharing is limited to paid plans and, per the support guide, to the web app for now. The documentation we read does not mention CalDAV, so third-party calendar clients are not an assured route.
Wrong for
A person who needs to merge a work Exchange calendar with a personal one in a single view, or who wants AI planning.

#3 Fantastical
Natural-language calendar and tasks for Apple and Windows · United States · flexibits.com
natural language Apple scheduling
Typing a sentence such as lunch with John on Tuesday at a given address and watching it become an event is still the fastest way to fill a calendar, and Fantastical built its reputation on it.
- Pricing: Per user / month. A permanent free tier, then Individual, Family and Team plans billed monthly or annually, each with a 14-day free trial. Free plan: free plan.
- Best for: Apple users wanting fast event entry
- Strengths: Natural-language event entry; iCloud, Google and Exchange accounts; Tasks with Reminders, Todoist and Google Tasks.
Where it falls short
Its strength is the Apple platform. Windows is supported but is newer, and the platform list we read names no Android app, which rules it out for mixed-device households.
Wrong for
An Android or Linux user, or a team that needs automatic focus-time protection.

#4 Google Calendar
Free calendar built into Google accounts and Workspace · United States · workspace.google.com
default Workspace sharing
Most people reach this calendar by default, and for many it is enough. Sharing is simple, tasks with a date appear alongside events, teammates can see working hours and locations, and almost every other calendar app on this list can read it, so choosing Google never traps you.
- Pricing: Free + Workspace plans. Free with a personal Google account, and included in paid Google Workspace plans, which add unlimited booking pages and Gemini features. Free plan: free plan.
- Best for: Anyone already inside a Google account
- Strengths: Shared calendars; Appointment schedules; Working locations and hours.
Where it falls short
Events are readable by Google, with no end-to-end encryption. The editing experience is slower than Fantastical's or Vimcal's, and Gemini features need a Workspace subscription.
Wrong for
Anyone who wants the schedule hidden even from the provider, or who wants smart auto-rescheduling.

#5 Microsoft Outlook
Exchange-based calendar inside Microsoft 365 · United States · microsoft.com
Exchange Microsoft 365 enterprise
Where Exchange runs the company, the calendar tends to follow. Outlook shows the free and busy times of colleagues when you invite them and proposes a slot through the Scheduling Assistant, and shared calendars come with Exchange Online without extra products. Microsoft Bookings adds an external booking page on plans that include it.
- Pricing: Bundled with Microsoft 365. Included in Microsoft 365 business plans with Exchange Online and offered free for consumer Outlook.com accounts; Bookings availability depends on the plan. Free plan: free plan.
- Best for: Companies running Microsoft 365
- Strengths: Scheduling Assistant; Shared calendars; Exchange free/busy lookup.
Where it falls short
The interface is heavier than the fast clients, and the calendar is tied to the email client in a way that irritates people who want only dates.
Wrong for
Freelancers and small companies on Google or Apple, who gain little by adopting an Exchange tool.

#6 Apple Calendar
Built-in calendar on Mac, iPhone and iPad · United States · support.apple.com
built-in iCloud Apple
Nothing else on the list asks less of you. Calendar is installed on every Mac, iPhone and iPad, reads iCloud and Google accounts in one place, lets you share calendars and send invitations, and shows scheduled reminders next to your events. Import and export are covered in Apple's guide, so leaving is straightforward.
- Pricing: Bundled with device. Included with Apple devices at no charge; iCloud storage plans are separate. Free plan: free plan.
- Best for: Apple device owners who want no extra app
- Strengths: Multiple accounts including iCloud and Google; Shared calendars; Event invitations.
Where it falls short
Availability follows Apple hardware, and we found no Windows or Android app in the guide we read.
Wrong for
A mixed-platform team, a Windows or Android user, or anyone who sells appointments.

#7 Vimcal
Keyboard-first calendar for heavy meeting schedules · United States · vimcal.com
keyboard-first time zones EA tools
Vimcal is built for the person who schedules forty meetings a week across continents. It reads Google Calendar and Outlook together, copies free slots into an email by dragging, converts time zones in the margin, merges duplicate events and sends booking links and polls.
- Pricing: Per user / month. A free iOS app. Free plan: free trial.
- Best for: Founders, executives and their assistants
- Strengths: Multi-time zone conversion; Drag-and-copy availability; Personal booking links.
Where it falls short
At $25 to $35 per month it is the most expensive single-user calendar here. The company is small, with a public address only in third-party records.
Wrong for
Casual users whose week has six meetings.
Visit Vimcal →
#8 Notion Calendar
Free Google Calendar client linked to Notion databases · United States · calendar.notion.so
free Notion menu bar
If projects already live in Notion, this is the calendar that closes a loop: deadlines in a database show up as events, and a page can be attached to a meeting and opened in one click. Notion bought Cron in 2022 and relaunched it under its own name in January 2024, keeping the keyboard-led, compact interface that made Cron popular.
- Pricing: Free. Notion states that the app is free for all users; some team functions follow Notion's own plans. Free plan: free plan.
- Best for: Notion users who plan inside databases
- Strengths: Google Calendar sync; Notion database items as events; Notion pages attached to events.
Where it falls short
The launch post names Google Calendar, Zoom and Google Meet as integrations, so Outlook and iCloud users have little reason to switch.
Wrong for
Teams that do not use Notion, or people whose primary calendar sits in Exchange.
Visit Notion Calendar →
#9 Reclaim.ai
AI focus-time and habit scheduler for Google Calendar · United States · reclaim.ai
focus time Google automation
Reclaim treats the calendar as something to defend. You set a focus-time goal, a lunch habit or a weekly review, and it finds slots, moves them when meetings arrive and shows the effect on your week. Scheduling links, buffers between meetings and time tracking sit beside that.
- Pricing: Per seat / month. Lite is free; Starter is $10 per seat per month billed yearly ($12 monthly), Business $15 yearly ($18 monthly), and Enterprise $22 yearly only. Free plan: free plan.
- Best for: Teams protecting focus time on Google
- Strengths: AI Focus Time; Habits; Task scheduling.
Where it falls short
The planner is only as good as your discipline about keeping tasks current, and moved blocks can irritate colleagues. Enterprise is not sold monthly and the free plan is deliberately thin.
Wrong for
Outlook-first companies and anyone wanting a standalone calendar.

#10 Zoho Calendar
Free calendar from the Zoho Mail team · India · zoho.com
free Zoho team calendars
Zoho Calendar is the least glamorous product in this ranking and one of the more complete. It offers a public booking page, team calendars that check availability, room and resource booking, video meetings through Zoho Meeting and sync with Google, Outlook, Apple and Thunderbird. Events import from iCal, CSV and Google formats.
- Pricing: Free. Described on the vendor page as a free online calendar for individuals and teams, and included for Zoho Mail, Workplace and One customers. Free plan: free plan.
- Best for: Zoho Mail and Workplace users
- Strengths: Appointment booking page; Team calendars with availability checks; Room and resource booking.
Where it falls short
The interface looks plain beside Fantastical or Notion Calendar, and the help text we read was a localized marketing page without detailed limits.
Wrong for
A user who wants a polished desktop client or smart time blocking, or a Google-only shop with no reason to open a Zoho account.

#11 Sunsama
Guided daily planner with calendar timeboxing · United States · sunsama.com
daily planning timeboxing tasks
Sunsama is less a calendar than a ritual wrapped around one. Each morning it asks you to pull tasks from your tools, drag them onto the day against your meetings, and check that the total fits. At night it prompts a short review. For a person whose problem is overcommitting rather than missing events, that discipline is the product.
- Pricing: Per user / month. Pro is $17 per month billed yearly or $22 monthly after a 14-day trial without a card, and Enterprise is by quote. Free plan: free trial.
- Best for: Knowledge workers who plan each morning
- Strengths: Guided daily planning; Calendar timeboxing; Unlimited integrations.
Where it falls short
It is not a primary calendar for teams. There is no free plan, so you pay from day fifteen.
Wrong for
Anyone who wants a quick view of meetings or a team scheduling product.
Visit Sunsama →
#12 Motion
AI task manager that auto-plans your calendar · United States · usemotion.com
auto-scheduling AI projects
Motion started with a clear promise: give it tasks, deadlines and meetings, and it builds your day, then rebuilds it when something shifts. That is still the core, but the product now bundles projects, docs, a wiki, a notetaker and an AI chat, priced per seat with monthly credits.
- Pricing: Per seat / month. The pricing page lists Pro AI from $19 per seat per month and Business AI at $29 per seat, both with a free trial and credit allowances. Free plan: free trial.
- Best for: Busy people wanting hands-off task scheduling
- Strengths: AI calendar and meetings; AI task planner; Projects and tasks.
Where it falls short
The calendar is now one module in a wider suite, and the price per seat climbs with the tier.
Wrong for
A person who wants only a clean calendar view, or a privacy-conscious buyer.

#13 Tuta Calendar
Encrypted, open source calendar from Germany · Germany · tuta.com
encrypted open source Germany
Tuta Calendar encrypts every calendar end to end, including notifications, and publishes free and open source clients for Windows, macOS and Linux, plus apps for Android and iPhone. It is sold by Tutao GmbH of Hanover, an independent German company, and calendars share with family or colleagues in a few taps.
- Pricing: Free + paid plans. The free plan includes one calendar. Free plan: free plan.
- Best for: Privacy-first users avoiding US providers
- Strengths: End-to-end encrypted calendars; Open source desktop clients; Free Android and iPhone apps.
Where it falls short
Fewer integrations than mainstream clients, and no unified view of Google or Outlook accounts. Paid plans are needed for more than one calendar, and the monthly prices were not visible on the page we read.
Wrong for
A person who needs to see Exchange or Google calendars alongside, or who wants AI planning.

Questions and answers
What is the best calendar app in 2026?
Morgen ranks first of 13, best for multi-account professionals on any desktop. Proton Calendar is second (privacy-focused individuals and small teams) and Fantastical third (apple users wanting fast event entry). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
Is there a free alternative to Google Calendar?
Several.
Which calendar app is the most private?
Proton Calendar and Tuta Calendar encrypt events so that titles, descriptions and guest lists are not readable by the provider. Proton is incorporated in Switzerland and Tuta in Germany.
Do calendar apps work with Outlook and Google at the same time?
Clients do. Morgen, Fantastical, Vimcal and Notion Calendar read several accounts at once, and Vimcal's own FAQ says it syncs with both Google Calendar and Outlook.
What is the difference between a calendar app and a scheduling tool?
A calendar app is where your events live and where you look at the day. A scheduling tool is the booking page that lets other people choose a slot.
Is AI time blocking worth paying for?
It helps when your work is flexible and most of your calendar is your own. Reclaim, Motion and Morgen place tasks into free slots and move them when the day changes.
What happened to Clockwise?
Clockwise announced that its team is joining Salesforce and that the product stopped being available on 27 March 2026.
Can I use Apple Calendar on Windows or Android?
We found no Windows or Android app. Apple Calendar is part of Apple's own operating systems, though its events live in iCloud and can be read elsewhere by exporting a file or subscribing. Fantastical lists Windows among its platforms.
Which calendar apps are made in Europe?
Morgen (Zurich) and Proton Calendar (Geneva) are Swiss, and Tuta Calendar is German, from Hanover. Swiss and German law govern what these vendors can disclose, which matters to a European buyer who has to document data location.
Will I lose my events if I switch calendar apps?
Not if you export first. Events can be exported as .ics files and re-imported by almost every service here, with Proton and Apple documenting import and export.
How much should a calendar app cost?
Nothing for the basics. Paid apps in this list start around $10 to $15 per seat or month on a yearly plan, with Vimcal and Sunsama in the high teens to mid twenties.
