Google Calendar, Microsoft Outlook Calendar and iCloud / Apple Calendar are the most popular free calendar apps available on the web. Let's compare them with the most secure one: the Tutanota Calendar.

Comparison of best free calendar apps

Free, widely used and with an extensive set of features, the calendars from Google, Microsoft and Apple make planning your events ever so easy. So does Tutanota. The encrypted email and calendar service also makes sure that no one can spy on your business meetings and personal events. For the first time, you can host your calendar online and be sure that no one but yourself can see your doctor's appointments or any other sensitive data in your calendar.

Qu'est-ce qui rend idéale une application calendrier ?

Apart from security and privacy, which to our understanding is a basic necessity, the most important need that a calendar has to fulfill is to help people get organized. Being able to schedule appointments (also with others), to add repeating events, to receive notifications about important events, and to look up birthdays are some of the most important features people need from calendar apps.

Before comparing calendar apps, we narrowed down the ones we wanted to include in this comparison to the mostly used calendars: Google Calendar, Outlook Calendar, iCloud / Apple Calendar and Tutanota Calendar. For the comparison, we focused on the following: A calendar app must be easy to use, well and functionally designed, enable users to send out invites and to share entire calendars. The calendar should also be available on all devices including browsers, desktops, smartphones and tablets so that you can keep track of upcoming events wherever you are.
