Living life by a calendar makes you work less, achieve more. I’ve hand-picked the best calendar apps for this very purpose. And if you feel that following a calendar is too mechanical, you’re not alone!  

Marlyn Munroe once said, 

I’ve been on a calendar, but I’ve never been on time. 

 If you can’t help but relate with Marlyn, you might want to try out a smart calendar app that helps you get time-efficient.   

In 2021, as routines shift back to normal and work moves out of the home, the need to fix upended workdays is deeply felt. 

Luckily, the best calendar apps in 2021 don’t just track dates but help you streamline your entire lifestyle. They help you proactively manage the loose ends in your schedule, replacing them with productive habits. 

A respite for everyone who wants 2021 to look more organized. 

I understand that not everyone uses their calendar for the same thing. Not everyone is marking their friends’ birthdays or crossing-off days leading to a sacrosanct MBA exam.  

You could be using your calendar for any of the following activities. 

  • For managing project (software, marketing, etc) timelines at your company or startup 🚀
  • Keeping track of your events and activities 🏃
  • Simplifying meetings with automated scheduling 😎
  • Boosting personal productivity 💪
  • Organizing professional work 🤓
  • Collaborating with your friends or co-workers 👤👥
  • One of the Best Calendar Apps for Android Users 👀
  • One of the Best Calendar Apps for iOS Users 🍎

So, let’s find the most suitable calendar app for you, one that solves your timing, productivity, or forgetfulness issues comprehensively. Here’s a list of some useful calendar apps that cater to your specific needs appropriately.

Just to be on the same page, let’s first discover what makes a calendar app truly great.  

What makes a great calendar app?

A great calendar app is most definitely the one that suits you the best. 

But while you’re checking out options, look for the following features that are hard to do without.

  • Solves Your Purpose – If you’re just looking to plan your week and be smart with your time, the calendar should do that first. Most calendar apps come loaded with tons of features but you don’t need all of them. Pick the one that solves your purpose in the best way possible. 
  • Cross-Platform – It’ll be a great advantage if the calendar app is accessible on your home PC, workstation, and other phones. Due to our dependence on multiple devices, having the same calendar app run on all of them is something to wish for.  
  • Integration-friendly – Calendar integrations such as Zoom meetings syncing with your iPhone or office holidays propping up on your personal calendar, are always welcome. Hence, look for a calendar that does offer integrations.
  • Clean Interface – Usability is the biggest concern for any calendar app. If you can read all your schedules in one shot and effortlessly glide your thumb over the calendar tiles – you’ve found the correct app. A clean interface reduces calendar stress.    
  • Affordable – While the price shouldn’t be a measure of quality, make sure your calendar app can justify what you’re paying. Some free apps are capable of wonders, but sometimes going for a paid option is actually the smarter thing to do.
