1. Google Calendar – Best Online Calendar App
With the integration of the entire Google suite, Google Calendar has got it all. Here, you can add tasks, color code your calendar events, and share them with contacts. Since Google Calendar is entirely cloud-based, it automatically syncs across all the devices using the same Google account.

Even though there is no native desktop calendar for Windows, you can add the Google Calendar widget to the Windows Calendar app and sync your Google Calendar through it. With this, you can easily balance your work hours by creating appointment slots, sending meeting invites, and coordinating with your entire team, all from the Windows calendar.
When creating an event, you can attach a location, set the reminder time, color code it, and, if necessary, add extra notes. Additionally, while Google has subscriptions for its Google Workspace services, this does not significantly impact the functionality and features of Google Calendar.
Pros
- Integration with other Google services
- Calendar sync features available
- Ability to create blocks in the schedule
- Using Windows Mail and Calendar app allows direct access to mail
Cons
- No native Windows app
- Fewer advanced features than other apps
- Platform Availability: Web, Windows, Android, and iOS
- Subscription: Free
2. Outlook Calendar – All-In-One Calendar App
Microsoft has an entire suite of products that include Word, PowerPoint, and Outlook. Running off OneDrive, Outlook Calendar‘s free calendar organizer can help you schedule and share events, synchronize tasks, and more. And the best part? It is free to use if you have a valid Outlook account.

While the app interface might appear simple at first glance, it’s anything but that. Moreover, you can access other Microsoft services like Word from the side menu.
You can also use the board feature to get an in-depth look at your tasks for the day. This will also allow you to create new entries, such as tasks or notes, and sync your calendar.
Furthermore, you can use the menu options to change your default calendar view. So, go crazy with this free calendar app. Start a new meeting, create multiple schedules, separate events using color-coded tags, and share what you want with others, even those who might not have a Microsoft account.
Pros
- Does not require a subscription
- Syncs across devices using the same Microsoft account
- Easy-to-use
- Event sharing is available for non-Microsoft accounts
Cons
- A Microsoft account is required
- Menu options can’t be customized
- Platform Availability: Web, Windows, Android, and iOS
- Price: Free
Note: You can also connect Outlook Calendar with Google Calendar to make the best of both worlds.
3. ClickUp – Best Calendar App for Business
ClickUp is much more than your regular calendar app. Here, you can create unlimited tasks, collaborate on documents, and create task management checklists. You can also change the task status and move it along once completed.
Further, you can assign a task level and add notes. Once the task is finished, mark it as complete to remove it from the list.

ClickUp lets you create new spaces and share them with other people. Here, you can create new to-do’s, add documents, and even create separate chat windows. You can browse all your currently active tasks in the My Work column. You can also use the whiteboard to sift through your tasks and efficiently track other things.
The ClickUp basic app has all the right features, but it can be confusing. Too many options at once can also be overwhelming, especially if it’s your first time using the service. We had to look through guides to better understand and use the app.
Here’s hoping that ClickUp adds interactive walkthroughs or other self-help tools in the future.
Pros
- Offers task customization
- Supports in-app video recording
- Live pulse overview and time tracking in the free version
- Good customer support
Cons
- The interface can be confusing
- Limited in-app help features
- Platform Availability: Web, Windows, macOS, Android, iOS, and Linux
- Price: Free | Paid Version: $5/member/month onwards
4. Any.do – Best Visual Calendar App
It’s never too late to switch to a better app. With that in mind, Any.do lets you import all current data from external services like ClickUp, Todoist, Asana, and more. The app interface lets you switch between daily, weekly, and monthly tasks. When collaborating with other people, you can also make your lists private.

You can add tasks to your calendar, assign a due date, and add tags after creating the task. By allowing you to turn your shared board private, Any.do ensure you’re always in control, even when working in collaborative environments. You can also create custom filters and add them to tasks.
Paid users also get access to other useful features like WhatsApp reminders, creating recurring tasks, and color tags for integration. You can also work in collaborative workspaces without limits to create project boards and add team members.
However, as a beginner, you might require some additional assistance to better understand these features.
Pros
- Multi-language support
- Calendar sync features
- Interactive walkthroughs and help videos
- Templates available
Cons
- The free version lacks WhatsApp reminders
- Customer support is not that great
- Platform Availability: Web, Windows, macOS, Android, and iOS
- Price: Free | Paid Version: $3/user/month onwards
5. Todoist – Most Popular Calendar App
One of the best cross-platform planner apps, Todoist lets you create tasks, prioritize them, and add due dates, labels, filters, and tags. These tasks appear in the sections below the corresponding date, giving you a glimpse of your schedule. Moreover, the added tasks sync and pop up in your calendar across devices using the same account.

The app interface has been designed with efficiency in mind, allowing you to easily toggle between monthly and daily task panels. You can then track your task’s progress and mark it as done to remove it from the daily agenda once finished. You can also change the panel appearance, create separate projects, and add tasks accordingly.
While the paid version of Todoist offers more features, such as automatic backups, shared team inboxes, themes, etc., it is better suited for professional use. The free version might be sufficient if you use Todoist as your personal calendar app.
Pros
- Cross-platform compatibility
- Calendar sync features
- Easy-to-use
- Supports Collaboration in the free version
Cons
- Automatic backups and reminders are unavailable in the free version
- Themes can’t be customized in the basic version
- Platform Availability: Web, Windows, macOS, Android, iOS, and Linux
- Price: Free | Paid Version: $4/user/month onwards
