Calendar apps compared
Comparison of best free calendar apps
What makes a good calendar app?
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 Tuta 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.
Tuta is open source so security experts can verify the code that protects your emails. Our Android app is Google-free making Tuta the best open source email service.

Tuta is the best free calendar alternative if you want to quit Google, Microsoft, and Apple and get rid of their extensive tracking of users. Tuta takes care of your data with automatic encryption and protects your privacy. We are committed to build the best calendar app while making sure that your business meetings and your personal events stay private at all times. Calendars contain some of the most sensitive data about our lives. It is time to protect this data.
