When it comes to shared calendar apps, Google Calendar stands out as the best overall choice.

It’s simple, intuitive, and packed with features that make scheduling seamless for individuals, families, and businesses alike.

As an app reviewer, I’ve tested countless free shared calendar apps, but Google Calendar continues to dominate because of its unmatched flexibility and integration capabilities.

One of the biggest advantages is its deep integration with Google’s ecosystem.

If you use Gmail, Google Meet, or Google Drive, your workflow becomes incredibly smooth.

You can create events directly from emails, set reminders, and even receive AI-powered suggestions for meeting times based on participant availability.

Plus, the ability to share calendars with different levels of permissions makes it perfect for coordinating with teams, partners, or even household members.

Another aspect that makes Google Calendar a top choice is its cross-platform availability.

Whether you’re on an iPhone, iPad, Mac, or even a Windows PC, you can access your calendar anywhere.

The color-coded event categories help keep things organized at a glance, and the smart scheduling assistant helps avoid conflicts when planning meetings.

While it’s not the most advanced tool for task management, it integrates well with third-party apps like Todoist or Notion for a more comprehensive productivity setup.

So if you’re looking for a reliable and free shared calendar app, Google Calendar is the best choice.

Unlike generic calendar apps, Cozi is designed with families in mind, offering a centralized hub for schedules, grocery lists, meal plans, and to-do lists.

What makes Cozi stand out is its family-friendly interface.

Whether it’s soccer practice, doctor’s appointments, or school events, Cozi ensures everyone stays on the same page.

Keeping a relationship organized can be tricky, especially when both partners have busy schedules.

That’s where Cupla comes in.

Unlike traditional shared calendars, Cupla is built exclusively for couples, helping them manage their schedules, plan date nights, and stay connected in a seamless way.

One of Cupla’s standout features is its shared calendar with automatic sync.

You and your partner can see each other’s availability in real-time, making it easier to schedule important moments together without conflicts.

Whether it’s planning dinner dates, anniversaries, or work schedules, Cupla ensures you never miss a beat.

Another great feature is its reminder and to-do list integration.

Additionally, Cupla includes a date planner tool that suggests ideas for spending quality time together.

Unlike general-purpose calendar apps, Cupla is designed with privacy in mind, ensuring that only you and your partner have access to your shared schedule.

4. Microsoft Outlook

It is perfect for businesses and teams.

Pros:

• Advanced scheduling tools for businesses and enterprises
• Shared calendar access with permissions and role-based controls
• Works seamlessly with email and task management in Outlook
• Enterprise-level security and compliance features

Cons:

• Slightly complex setup for new users
• Not as visually intuitive as some alternatives

Price: Free, $9.99/month, or $99.99/year (Microsoft 365 Family plan).

Get it from: App Store

For businesses and teams, Microsoft Outlook is a powerhouse when it comes to shared scheduling and collaboration.

It’s built for professionals who rely on Microsoft 365 tools like Outlook, Teams, and OneDrive to keep their work organized.

What sets Microsoft Outlook apart is its robust scheduling capabilities.

You can create team-wide shared calendars, set different permission levels for users, and even automate meeting scheduling with AI-driven suggestions.

It’s especially useful for companies with remote teams or large organizations that need precise control over event visibility and resource allocation.

The deep integration with Microsoft Teams and Outlook email makes it a go-to choice for businesses.

Scheduling a meeting directly from an email thread, attaching relevant files from OneDrive, and sending invites with automatic timezone adjustments ensure smooth workflow management.

Additionally, Outlook’s built-in task and reminder system helps keep team members on track.

For security-conscious businesses, enterprise-grade encryption and compliance features ensure that sensitive data stays protected.

While the learning curve might be steep for non-business users, Microsoft Outlook is undeniably the best shared calendar app for businesses and teams.

5. Apple Calendar

It’s a go-to choice for those deeply immersed in the Apple ecosystem.

Pros:

• Seamless integration with the Apple ecosystem
• Siri voice commands for hands-free scheduling
• Simple, clutter-free interface with color-coded events
• Works offline and syncs effortlessly across devices

Cons:

• Lacks advanced collaboration features for teams
• Only available on Apple devices

Price: Free

Get it from: App Store

If you’re deep into the Apple ecosystem, there’s no need to look further than Apple Calendar.

It’s built right into your iPhone, Mac, iPad, and even your Apple Watch.

As someone who reviews apps constantly, I’ve tested plenty of third-party calendar apps, but Apple Calendar remains the best choice for those who want a simple, reliable, and hassle-free scheduling experience.

What makes Apple Calendar great is its seamless synchronization.

The moment you add an event on your iPhone, it appears instantly on your Mac or iPad.

Plus, Siri integration lets you add events with just your voice.

Whether you’re setting a work meeting, a family dinner, or a workout reminder, a quick “Hey Siri, add a doctor’s appointment for Friday at 3 PM” gets the job done in seconds.

Another reason Apple Calendar is a solid pick?

It works offline.

Unlike Google Calendar, which struggles without an internet connection, Apple Calendar lets you view and edit events even when you’re off the grid.

And since it syncs effortlessly with iCloud, Google Calendar, and Microsoft Outlook, you’re not locked into a single ecosystem.

The downside?

If you need advanced collaboration tools for work or large teams, you might find it a bit basic.

But if you’re into the Apple ecosystem and need a clean, efficient, and free calendar that syncs everywhere, Apple Calendar is a no-brainer.

If you’re looking for a smart shared calendar that does more than just remind you of meetings, Calendar.AI is the perfect choice.

It’s an AI-powered scheduling assistant that helps you plan meetings efficiently, analyze attendees, and even pull insights from LinkedIn and CRM tools.

What makes Calendar.AI stand out is its ability to streamline scheduling without back-and-forth emails.

It automatically detects available time slots and suggests optimal meeting times based on participants’ calendars.

If you’re constantly juggling meetings, this feature alone can save you hours each week.

But what really sets it apart?

AI-driven meeting insights.

It even provides agenda suggestions and automated meeting notes, making it an excellent tool for professionals who need to stay on top of their schedules.

However, while Calendar.AI is great for business, casual users or families may find it too complex.

Plus, the best AI-powered features are locked behind a paid plan.

If you’ve ever tried planning a group outing, you know how frustrating it can be.

Endless messages, scheduling conflicts, and last-minute cancellations.

That’s where Howbout comes in.

Unlike traditional shared calendar apps designed for work or family use, Howbout is made specifically for friends and social groups, making it the best choice for staying connected and planning events effortlessly.

One of the best things about this free social calendar app is its real-time availability feature.

With this shared calendar, you and your friends can mark your availability, and the app will suggest the best time for everyone.

Another standout feature is its built-in group chat.

8. Fantastical

A premium calendar for work-life balance.

Pros:

• Beautiful, intuitive design with natural language input
• Smart scheduling for work and personal events
• Integrates with multiple calendar services
• AI-powered scheduling and automatic time zone adjustments

Cons:

• Premium version required for full features
• Slight learning curve for new users

Price: Free, $6.99/month, or $56.99/year.

Get it from: App Store

If you’re like me, juggling work, personal plans, and everything in between, you know how messy scheduling can get.

That’s why I love Fantastical.

It doesn’t just keep track of events, it actually makes planning feel effortless.

What really sets Fantastical apart is its natural language input.

Instead of clicking through menus to add an event, you just type something like, “Dinner with Alex at 7 PM next Thursday,” and it’s on your calendar.

It’s little details like this that make a huge difference when you’re constantly on the go.

Another thing I appreciate is how well it manages multiple calendars.

I’ve tested plenty of apps that claim to keep work and personal schedules separate, but Fantastical does it better.

You can see everything in one place without it feeling cluttered.

Plus, its AI-powered scheduling suggests the best times for meetings, so you’re not stuck in endless back-and-forth messages trying to find a slot that works.

Now, here’s the catch.

Fantastical’s best features are locked behind a premium subscription.

The free version is decent, but if you want team scheduling, weather integration, and advanced task management, you’ll need to pay up.

Is it worth it?

If you’re serious about balancing work and personal life without losing your mind, then absolutely.
