We will take that into account to dissect what each one offers and that you find the calendar that best suits your needs .

All of us trust our gadgets when it comes to keeping track of the events and activities that happen in our lives. This is why calendar apps have become so important in our lives. There are a ton of calendar apps on the Google Play Store . However, finding a free app that is good in terms of features and design can be an odyssey, as it may not suit what you’re looking for, because it doesn’t provide you with a pleasant experience, or because it doesn’t integrate effectively. with your Android device. Due to this, we have compiled five calendar applications that we have found to be the best on the market and that may also satisfy you

What we say about the Calendar app?

There are those who cannot live without the year view and there are those who always use the agenda view. In order to compare what each calendar application offers, we must take into account several common factors. In our comparison we will analyze these aspects of each application:
  • Personalized reminders : When the time comes for an event, you probably want to know ahead of time. Some applications allow you to choose precisely when you want to receive that notification. Others, like Google Calendar, include their own section to create reminders.
  • Holidays and birthdays : Some calendar apps add local holidays to your contacts’ calendar and birthdays on their own, without the need for them to be added to your mobile as an additional calendar.
  • Calendar views : As a general rule, the more views a calendar application has, the better, because it is more likely to include the one you use frequently. The most common are weekly and monthly, although some apps also include the annual or multi-day view.
  • Tasks : Tasks and calendars are two closely related concepts, with the main difference that tasks are not always linked to a date and can be completed. It is common for calendar apps to include the task feature, although it is not available in all.
  • Synchronization : All applications are synchronized with the calendars available on your mobile, although some can connect with other services on their own, as well as synchronize events on their own so that you can consult them on other mobiles or on the web.
  • Widgets : All the applications in our comparison include at least one widget for the desktop, although some go a step further with various designs and different views, to better adapt to what you are looking for.
  • License : Our list is entirely made up of free calendar apps, though some offer all their features for nothing, and others reserve a handful of them for paid versions.
Taking all of the above into account, we have compiled our list with the seven best calendar applications of the moment . They are mostly specialized calendar applications, although we have also included Microsoft Outlook, being the spiritual heir to Sunrise Calendar , may he rest in peace.

best free calendar apps list for android & iOS 2021

Below we list what, in our opinion, are the best calendar applications:

1.Google Calendar

As it could not be otherwise, we started with Google Calendar, the application to beat due to its competition, due to the mere fact that it is pre-installed in the vast majority of occasions.
Google Calendar is a calendar application that is hard to find fault with. Its design was relatively recently renovated and it marks practically all the boxes of what can be asked of an application of the style, except perhaps one: incomprehensibly, it does not include tasks . Despite the existence of Google Tasks.
The Google Calendar stands out from the rest by reusing the Google muscle to integrate events from Gmail and add local holidays and birthdays of your contacts. Although it has no tasks per se, it allows you to create reminders, which is something like simpler events.

2.Any.do Calendar

Any.do is a name that sounds strong when talking about note and to-do apps , although they also have their own calendar app. At Any.do. Calendar is something like a memo and calendar application united in a single app.

3.Calendar App – Google Calendar & Calendar Widget

The app has a pleasing design to look at, although some will certainly miss showing events directly in month view, something not available. As a calendar application, it does not have as much depth of options as other alternatives , although instead it wins in other related functions.
Any.do keeps some functions under its arm for its paid version (3.29 euros per month), although it has interesting additions for its free users, such as a quick shortcut to create the shopping list .

4.Microsoft Outlook

Microsoft Outlook is not an especially light application (its latest version exceeds 270 Mb of storage), so it is not the lightest alternative if you are only interested in the calendar function and not the mail client. Now, if you already use Microsoft Outlook on your mobile , its calendar section is an alternative to consider.
Microsoft bought Sunrise Calendar in 2015 and promised that its legacy would live within Outlook. Years have passed, and the Outlook calendar can be found few drawbacks , beyond that it is a tab within a larger application and not a separately accessible application.
Microsoft Outlook has its sights set on something more for the business audience, synchronized with various services such as Evernote or Wonderlist. One point where it limps from the competition is in the number of widgets available (only one) and where tasks are not currently displayed as they appear in Outlook for PC.


TimeTree is a slightly less known calendar application than the previous ones. As best assets, it has a fairly clean design -similar to Google Calendar- and the possibility of sharing calendars with other people , including social functions such as comments and “likes”.
Internally, TimeTree works a little differently than other calendar applications. Here the calendar is not synchronized from the mobile as it is, but you can import the mobile’s calendars to use them in the application, although the changes you make in TimeTree will not be visible from other applications. The application has its own section to create notes (with an associated date or not) and that, like calendar events, can be shared with other people. At the moment it includes holidays in 13 countries.

6.Business Calendar

Business Calendar is one of the most popular calendar apps on Google Play, with more than 5 million downloads and an average score of 4.6. Visually it is not a treat for the eyes, but instead includes a lot of settings and customization options .
Business Calendar has a lot of everything, including types of views. You will find in it the coveted annual view (with different colors depending on how busy the day was), including holidays, birthdays and week numbers. All this, being able to largely modify the final appearance (although some of these options are limited in the free version).
In Business Calendar there is also space for tasks , which can be associated with a location and with a personalized reminder. The widgets are not lacking either: there are seven in total, including with agenda, monthly, weekly and tasks views.


ZenDay is one of the most curious calendar applications. Its main interest lies in its peculiar way of displaying the calendar: with a 3D view in which you can consult your agenda in a way that you will not find in the competition
ZenDay also has a more traditional way -in 2D- to show your calendar, although this mode is only available with the mobile in landscape and includes the monthly and weekly view. The most paradoxical thing is that, except for the futuristic 3D view, the rest of the application has a more worthy five-year-old design. ZenDay does not show you holidays or birthdays, although it does have a task section (with a duration and custom actions). Other curious functions are the Coaching and Debriefing section, with statistics and information about your events.


When you open the Digical calendar application, you can enjoy its elegant white interface that includes a dark upper bar thanks to the Holo Light theme. You can go to the dark side, if you prefer, by changing the application preferences. Aside from the various themes, Digical also features an impressive calendar layout, customizable lock screens, built-in location search, integration with Google Now, and improved notifications .
