2021 is officially the year of calendar apps. Calendars, of course, show you your schedule. Every calendar app manages that; the best calendars, however, aren’t just functional. They give you clarity about how you spend your time, and we all know time management is crucial.

For personal users, a calendar app can simply be useful, but for business users a calendar app is essential. For business purposes, it can be a great way to cover all that, as well as, more important issues such as deadlines, meetings, and events.

What makes a calendar app great?

In looking for the best calendar apps, we should look if they have the following characteristics:

Easy to use

A very important feature that determines how good any app is how easy it is to use. That is in fact the priority of most developers so that integration into the software is easy for users which in turn makes it have higher retention rates. Calendar apps are easy to use when they require minimal clicking and are easy to navigate. They should be simple to use and should not necessitate a lot of attention. It shouldn’t feel like a hassle when you start using a calendar app as it can be a huge productivity killer.

Can integrate with other apps

The best calendar applications will not only work on their own but will also integrate with other important apps you use, such as email and office software. That way you can get sent notifications in good time of anything coming up on your calendar.

Has a bunch of features

Power features, such as configurable views and integrations, will help you get the most out of your calendar if you’re a serious scheduler. For apps with less functionality, look for customization options that allow the program to adapt to your preferences.

Available for multiple devices

Apps that are accessible on more than one platform will always be more preferable. You should be able to see your calendar regardless of where you are or which device you are using.

Simple to share

You probably don’t work alone, and your calendar shouldn’t either. You can share appointments or even your full calendar with the best apps.

What are the top 5 calendar apps?

1. Google Calendar

Google Calendar is the OG application. Its popularity stems from the fact that you can create multiple calendars in one place using a Google account, which almost everyone has. Those entries can then be transported to almost any other online calendar.
