If you're seeking alternatives to Google Calendar, you've come to the article you need!

Well, it's certainly a tool that countless people worldwide rely on to manage their schedules effectively. So let’s move into a detailed description.

You might even recall a time when calendars were printed on paper and displayed on your kitchen wall. In what seems like an instant, computerized calendars that can sync with one another have become ubiquitous, benefiting businesses everywhere.

However, with ever-present questions over safety from hackers and how developers such as Google use your data, more and more organizations are looking to Google Calendar alternatives.

Top Google Calendar Alternatives You Must Try

If you have in mind that Google Calendar is suitable for everyone and every organization, you are mistaken. We have prepared a selection of the best scheduling apps for specific use cases. Each of these tools has earned a strong user base and incorporates the key features necessary to organize your projects. By choosing the service to manage your time, you get a complete solution for your work schedule. So we will describe the options, and then you can find the ideal alternative to Google Calendar for your company. Let’s roll straight into the topic!

Why companies are moving away from Google Calendar

As businesses seek more security, flexibility, and advanced scheduling features, many are looking for Google Calendar alternatives that better fit their needs.

Specific data privacy and security needs

Google’s ecosystem relies on cloud storage, raising concerns about data security and third-party access. Although leading cloud hosts are secure, some companies have specific requirements for their sensitive information and prefer self-hosted calendar solutions to keep full control over their data.

Lack of customization and advanced features

While Google Calendar covers the basics, it lacks deep customization options for businesses that need tailored workflows. The best scheduling apps for businesses like Bitrix24 offer features like task automation, project management integration, and AI-powered scheduling.

Better team collaboration and scheduling tools

Google Calendar works well for individuals but has limited team calendar management capabilities. Businesses need tools that balance meetings, allocate resources, and coordinate across time zones. Many cross-platform calendar apps now include automated scheduling, availability tracking, and teamwork, making them a better fit for small and growing teams.

Rising subscription costs and pricing concerns

Google Calendar itself is free, but advanced business features are locked behind Google Workspace subscriptions. Many companies prefer open-source calendar software or self-hosted calendar solutions to avoid ongoing fees. For businesses scaling their operations, solutions with one-time payments or more flexible pricing can be more cost-effective.

Overloaded and cluttered interface

Google Calendar, while functional, becomes difficult to navigate with multiple shared calendars, meeting invites, and external integrations. Many businesses switch to Google Calendar alternatives for businesses that provide a cleaner, more intuitive design, helping teams focus on what matters without unnecessary distractions.

1. Bitrix24

Bitrix24 offers either cloud-based appointment scheduling or a self-hosted Google Calendar alternative with a vast array of other business tools natively integrated with your scheduling app. Setting up a call with a client? Bitrix24’s AI CoPilot automatically transcribes the meeting and creates follow-up tasks based on the content of your meeting.

The variety of use cases provided along unlimited calendars you can use individually, on a team-level, or over the company as a whole give you ultimate flexibility. It’s great for growing organizations too, with one price tag for unlimited users and support for both the cloud and open-source calendar software.

With built-in team calendar management, Bitrix24 makes it simple to coordinate meetings, assign tasks, and track project milestones all from a single platform. Unlike standalone calendar apps for business, it syncs seamlessly with task management, document sharing, and CRM tools, fully integrating your scheduling efforts into your daily workflow. Whether you're managing client appointments, team stand-ups, or long-term project planning, Bitrix24 provides a scalable, all-in-one solution that grows with your business.

2. Microsoft Outlook Calendar

Along with Google, Microsoft Outlook Calendar is one of the standard-bearers of free online calendars. You can run a bunch of team calendars at the same time and share them with others or view them to see when there's an available slot for a meeting.

An obvious choice for teams already using Microsoft tools, this Google Calendar alternative combines well with native email, video conferencing, and docs to keep most of your work in one place. But despite being one of the world's most recognizable names, it doesn't match the breadth of capabilities that Bitrix24 offers. That said, it's a clean and responsive interface that will make scheduling a breeze.

3. Teamup Calendar

Moving into the Google Calendar alternatives that aren't exactly household names, Teamup is great for organizations that need a customizable framework for their scheduling needs. It's well-designed for companies of all sizes and, with time zones accounted for and the ability to sign one event to multiple calendars.

Teamup is all about flexibility, which you can see through the 11 different views. With that, each of your team members can adapt it to what suits them best, zooming in for the minute detail and taking a step back for a broad look over a month or a year.

4. TimeBlocks

TimeBlocks has realized the importance of usability when producing a Google Calendar alternative, and they’ve included a range of features to that end. When you’ve got a packed day or week, the app will automatically zoom in to give you a clearer view. This stops the annoying need to go to drop downs or use finger commands.

The drag-and-drop tool is great for quick scheduling on your mobile or desktop, and even if everyone else is using Google, you can sync those calendars to get the best of both worlds.

5. Cal

Any.do already had a calendar in their task management software when they decided to create Cal, the app designed specifically for scheduling and organizing your timetable. Like other Google Calendar alternatives, you can add locations to your events, whether through physical maps or virtual video call links.

It has a beautiful user interface and you can add photos to your meetings to spice them up a little. Similarly, you can attach notes so everybody is prepared in advance.

6. DigiCal Calendar Agenda

DigiCal puts a focus on the real-world environment around their appointments. With integrated weather forecasts and a location search, it’s a great app for jobs where you can face the elements, such as event planning and travelling sales.

DigiCal doesn’t have quite as many views as Teamup, but seven calendar visualizations and six widget views still allow your team to adapt their calendar to what suits them. Similarly, you can get going in no time with nine templates for your widget themes that you can go on to customize based on your strategy.

7. TimeTree

TimeTree works just as well for work within a company as well as for your free time and family outside the office. A simple tool without many stand-out features, it does what you want a calendar to do, but not a great deal more.

This doesn’t make it a particularly bad option, however. It is perfect for a bare-bones team where all you need is a simple scheduling app. One extra that goes with your calendar is the shared notes and lists feature, so you can prepare for meetings and take notes like a pro.

8. Zoho Calendar

Like Bitrix24 and Microsoft, Zoho is one of those Google Calendar alternatives that links up other proprietary apps in an effort to give that all-in-one offering. However, using Zoho apps as the building blocks of your business can get quite pricey, with many apps paid for individually.

That said, it gives you everything you want out of a team calendar, with scheduling, sharing, and syncing. You can also embed your calendars when building your website to give as a handy tool for event planning. Put simply, if your team is already up and running on Zoho, it’s a smart choice.

9. Edo Agenda

Edo Agenda includes basic task management tools to its calendar offering so you can be more meticulous in the meetings and appointments you schedule. You couldn’t really call it a project management app, but the to-do lists and reminders can keep you and your team on track.

Aimed at freelancers, you can get a decent idea of your productivity in the Planner feature, and you can get a lot of those features in the free version, with more unlocked on paid accounts. One feature that freelancers love are snippets, where you can quickly take down notes about new ideas or projects and save them to your calendar.

10. Jorte

Jorte is all about customization, with themes and color schemes that you can adapt to make the calendar more attractive. You can even mirror your company’s branding, which works well if you’re embedding your calendars on your website.

It’s a great Google Calendar alternative for those who want to stay up to the minute. You can integrate it with news websites and weather updates to get your feed of information as you plan out your day.

11. Nextcloud Calendar

Like Bitrix24, Nextcloud Calendar gives you a self-hosted Google Calendar alternative so you can keep total control over your own data. If security concerns are why you’re looking to move away from the big names, Nextcloud is a smart option.

You get pretty impressive features along with your calendar, such as file storage and sharing, instant messenger, emailing, and even video chats. While it doesn’t have quite the same breadth of uses as Bitrix24, it still goes above and beyond many of the other products listed here.

12. Cozi

Cozi is the first on this list that isn’t designed for businesses, although it is quite capable of working for them. Instead, it was created as a family-focused app, combining to-do lists, birthday trackers and a calendar that everyone can use. Each schedule comes in a different color for easy identification, and you can automate reminders to keep everyone on track.

With its emphasis on family life, Cozi comes with recipes and meal planners that you can add to as you go. That in turn informs your shopping lists, another feature that gives you one less thing to remember.

13. Business Calendar 2

Business Calendar 2 is made to be as user-friendly as possible, and while it might take a little while to get used to, it can make you considerably more agile when you’re on the go. For example, one swipe can take you from a one-day to a 14-day view, and tap to get quick-view details for each event.

There are seven widgets that you can attach to your home screen, saving you time in the morning as you check your to-do list for the day. As an additional extra, you can attach files and photos to your activities to add context.

14. Apple Calendar

Anyone who is used to iOS products will have no problem working their way around Apple Calendar. Even new users will be able to handle its super-easy interface that you could mistake for a Google app without the primary colors. You can create events with invites, locations, FaceTime links, and alerts across a range of synced calendars.

However, Apple Calendar shares a drawback of its Google counterpart. If your team isn’t all connected to Apple products, you’re going to find a lot of difficulty in your organization.

15. nTask

nTask is primarily designed for project management, but all that is based around a powerful calendar tool. You can create meetings and appointments with just a few clicks of a button, and schedule tasks in preparation or as a result of your events.

Another of our open-source options, Proton Calendar is a free app that doesn’t come with a bunch of ads and dubious data dealings, and uses end-to-end encryption for further security.

Not exactly bursting with features, it does cover all the basics to make our list of Google Calendar alternatives. Therefore, you can get a range of views, launch recurring events, put widgets on your homescreen, and set notifications and reminders. However, you can’t create notes related to your tasks or import your data from calendars you’ve used in the past.
