Apple Calendar vs Tuta Calendar

Apple Calendar

• People with an iPhone, iPad or Mac who want a calendar at no cost
• Seeing iCloud, Google and Exchange calendars side by side
• Families and friends sharing an iCloud calendar

Tuta Calendar

• People who want a calendar their provider cannot read
• Tuta Mail users who want email, contacts and calendar in one account
• Linux users looking for an open-source desktop calendar client

Apple Calendar

• Apple's setup guide covers iPhone, iPad, Mac and iCloud.com, with Windows handled by syncing to Outlook through iCloud for Windows. No Android app is listed.
• Calendar on iCloud.com needs a tablet or computer; Apple's guide says it cannot be used from a phone browser.
• Editable sharing is limited to iCloud calendars and people with iCloud accounts. Everyone else can only view a public, read-only calendar.
• Time-to-leave alerts are not sent for destinations more than three hours away, and travel time does not update when an event's location changes.

Tuta Calendar

• The Free plan includes one calendar and has no calendar sharing, event invitations or offline support.
• Calendar has no subscription of its own: paid features come with Tuta's paid personal or business mail plans.
• Prices are listed in euros: personal plans include taxes, business plans exclude them, and totals can vary with payment platform fees and exchange rates.
• Other calendars are brought in by import; the calendar page mentions no two-way sync with Google or Outlook calendars.

Apple Calendar

Several accounts in one calendar

Add iCloud, Google, Microsoft Exchange and other CalDAV accounts and see their events together in List, Day, Week or Month view, with a color for each calendar.

Natural-language event entry

On Mac, typing a phrase such as "Football Game on Saturday from 11 am - 1 pm" creates the event with its date and time filled in. Siri can add or change events by voice.

Travel time and time-to-leave alerts

Adding a location attaches a map and weather, and Calendar sends an alert when it is time to leave, based on traffic or transit conditions. Travel time can be added to the event's duration.

Shared and public calendars

Share an iCloud calendar with other iCloud users as view-only or editable, or turn on Public Calendar so anyone with the link can view and subscribe to it.

Reminders next to events

Scheduled reminders from the Reminders app appear on the calendar, where they can be created, edited and marked complete.

Invitations and video call links

Send and answer invitations through iCloud, Exchange and other accounts. Events can carry a video call link, a FaceTime call on Mac, attachments and notes.

Tuta Calendar

End-to-end encryption

Events, invitations and shared calendars are encrypted end to end with what Tuta calls quantum-safe encryption, so the provider cannot read them.

Encrypted reminders

Event reminders arrive as push notifications on phones and computers. They are sent encrypted and kept hidden from the phone's operating system.

Calendar sharing

On paid plans a calendar can be shared with family or colleagues with read only, read and write, or write and manage sharing rights.

Event invitations

Paid plans can send and receive calendar invitations, and can send one encrypted to someone outside Tuta using a shared password.

Apps on every platform

Apps for Android and iPhone, open-source desktop clients for Windows, macOS and Linux, and a browser version. The Android app is also offered through F-Droid.

Built into Tuta Mail

The calendar shares an account with Tuta's encrypted email and contacts, and existing calendars can be imported in the settings.
