What date is it today?

Imagine answering this question without a calendar.

You can use them to create project timelines, plans, set due dates, reminders, and more.

So which calendar app should you use?

In this article, we’ll highlight the five best calendar apps in 2021, along with their key features, pros, limitations, and pricing.

Mark your calendar because today, we’ll help you find the best calendar app!

What Makes a Calendar App Great?

Most calendars will tell you the date. 

Maybe even help you set reminders and schedule an upcoming event. 

But those are just the ABCs.

The big question is, what else?

When choosing an excellent calendar app, here’s what you need to look out for:

  • Shareability: offers shared calendar options to share with your team  
  • Customization options: lets you personalize the tool to suit your taste
  • Ease of use: user-friendly, intuitive, and easy to learn interface 
  • Device support and sync: should support all your devices and offer cross-device sync

If your calendar can do all this, lock it down. 🔒

ClickUp is one of the world’s highest-rated productivity and project management tools used by startups, tech giants, and even freelancers.

It’s #1 on our list of best calendar apps and event management software thanks to the powerful Calendar view

The Calendar view is the ultimate team calendar. 

Use it to plan projects, manage resources, and schedule tasks with ease.

It’s super flexible, and you can choose the format you see things in, like:

  • Day: view an entire day’s tasks and events
  • 4-days: view a rolling four day period
  • Week: view a whole week of scheduled tasks
  • Month: get an overview of an entire month
  • Work week (mobile app): view Monday to Friday only
  • Schedule (mobile app): view a multi-day continuous layout

And what really makes ClickUp one of the best free calendar apps is that you can do way more than just manage events and schedule meetings. 

Here’s a sneak peek of what’s in store for you. 👀

ClickUp key features

A. Carry your work anywhere with the Mobile Calendar View

Unlike a lot of software, ClickUp’s Calendar is easily accessible on your mobile phones and well-optimized for it.

Not only can you view and edit your tasks and set due dates as far out as you want, but also:

B. Reschedule tasks using the Calendar view

No more entering dates manually to reschedule tasks.

Just drag and drop the task you want to reschedule to the new date in the Calendar view.

You can even schedule recurring tasks and preview when it recurs in the Calendar view.

C. Never miss an important event using reminders

Missing a client meeting, forgetting to submit a report… 

Scary thoughts, right?

Not if you’ve got ClickUp. 

Here, you can set reminders with attachments for context.

You can even curb those ‘ping’ sounds with custom notifications for your reminders. 🔔 

You decide which activities trigger a notification and when.

D. Don’t miss deadlines with due dates

Chasing deadlines is already tiring.

Keeping up with them just adds to the trouble. 

Give your brain a break and let ClickUp track your deadlines so you can focus on meeting them.

To add or adjust due dates quickly, just drag and drop tasks on the Calendar View.

E. Set task urgencies with Priorities

Imagine building the roof of a house before you make the base. 

This may work with a Lego house, but it’s no way to build.

Right, Bob?

Bob the builder saying exactly

That’s why you need Task Priorities. 

They help you start with the most important tasks first and then move things along.

In ClickUp, you can set your tasks as urgent, high, normal, and low.

Priorities appear on your Calendar view task cards so you can decide how to structure your days.

F. Plan projects using multiple views

The Calendar view didn’t work for you? No problem.

Try the Timeline view

It’s a more linear way to visualize your work.

Customize as much as you want with grouping and filtering options based on assignees, Priorities, Tags, Custom Fields, etc.

ClickUp also has many other views, including:

  • Board view: see tasks in columns that represent different Task Statuses
  • List view: view tasks in a list format
  • Workload view: visualize and manage your team’s work capacity 

G. Keep people in the loop with Public Sharing

Sometimes you come across clients, stakeholders, or even vendors that may not be part of your workspace. 

But should that stop you from updating them?

Keep people in your Workspace and outside in the loop using Public Sharing. You can share all the views, including the Calendar and Timeline view, with them!

H. Stay synced with Google Calendar integration

Google Calendar loves to get along with ClickUp.

2. Apple Calendar

Apple calendar

Apple Calendar or iCal is for all the Apple fanatics in need of a personal, work, or family calendar. 

This iOS calendar app usually comes pre-installed on Apple devices, so you can ditch the App Store search.

Apple Calendar will keep everything synced between your MacBook, iPhone, iPad, Apple Watch, and probably other future Apple devices that they may invent.

An Apple coffee maker, anyone?

Unfortunately, the iOS calendar is an exclusive club that Windows and Android can’t access.

With the same Google account, you can access the free standard version of any Google App, including Google Sheets, Drive, Docs, etc (hint: you could even create a calendar in Google Sheets or Google Doc!).

And when it comes to integrations with productivity tools, this popular calendar app is super flexible.

Maybe that’s why it integrates with other productivity tools so easily! 🤭
