Pick fruux if
- Fits if you want calendars and contacts in sync across phone and laptop
- Works for small teams that need shared address books
Look elsewhere if
- Tight if you stay free: Basic stops at 2 devices and 2 shares
- Not for you if you want a calendar app, since fruux publishes no native apps in what we read

Pick Tuta Calendar if
- Fits if you want a calendar that its own provider can't read
- Works for people who already use Tuta Mail and want email, contacts and calendar in one account
Look elsewhere if
- Skip it if you need it kept in step with a Google or Outlook calendar, as it only imports
- Tight if you're staying free and want to send invitations, share a calendar or work offline
- Not for you if you only want a calendar, since the paid features come with Tuta's mail plans
- Too light for linking other tools, as Tuta Mail is its only connection and no API is listed
- Watch out: prices are in euros, with taxes included on personal plans and added on business plans
How we grade them
| 2.8GPAfruuxGood | 2.4GPATuta CalendarFair | |
|---|---|---|
| Value for money | BPro is €4 a month or €40 a year, under the category's $4.99 cheapest quarter. Team is €20 a month for 5 members. | BTuta's lowest paid personal plan is €3 a month paid yearly, €3.60 monthly, taxes in, which lands in the cheaper quarter of calendar tools. And that buys Tuta's encrypted email, unlimited calendars and 20 GB of storage as well, because the calendar isn't sold on its own. |
| Free plan and trial | BBasic is free with unlimited contacts, calendars, tasks and storage, limited to 2 devices and 2 shares. | COne encrypted calendar and 1 GB, with apps on every platform. But no calendar sharing, no event invitations and no offline support, so it's a calendar for you alone. Not being able to invite anyone to anything is a cap you meet on day one. |
| Features | CIt does one job, sync, and does it fully, which is a smaller job than a calendar app. Free-busy, out-of-office and delegation need a compatible client because the web app does not support them yet. | CEnd-to-end encryption on events, invitations and shared calendars, reminders hidden from your phone's operating system, and sharing with read or write rights on paid plans. Beyond the encryption it's a plain calendar, and the listing's own gap is the big one: other calendars come in by import, with no two-way sync. |
| Ease of use | CNo store rating on record. You set up accounts on each device through its own sync settings. | CNo store rating on record, and getting started means opening a Tuta account first, because the calendar isn't sold separately. Old calendars have to be imported in the settings rather than connected. |
| Platforms and integrations | AWeb, Mac, Windows, Linux, iOS and Android through standard clients, plus Thunderbird, Fantastical, BusyCal and Outlook, and a developer API. | BWeb, Windows, macOS, Linux, iPhone and Android, with the Android app on F-Droid too. But the only thing it connects to is Tuta Mail, and no API is listed. |
| Best for | syncing calendars and contacts over CalDAV | a calendar your provider can't read |

Worth knowing
fruux
- Free accounts stop at 2 devices and 2 shares; Pro raises these to 10 devices and unlimited shares.
- Prices are in euros, and there is no US dollar price.
- Free-busy, out-of-office and delegation features need a compatible calendar application, because the web app does not support them yet.
- fruux does not publish its own native apps in what we read; it relies on the devices' own CalDAV and CardDAV clients.
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.

- Other calendars are brought in by import; the calendar page mentions no two-way sync with Google or Outlook calendars.
Key features
fruux
- Standards-based sync
- Syncs through CardDAV and CalDAV, so apps such as Apple's built-in ones, Thunderbird, BusyCal, Fantastical and eM Client can connect without a fruux app.
- Contacts, calendars and tasks
- All three data types are kept together, with search, multiple task lists and filtering, calendar views and a web app.
- Sharing and public calendars
- Share calendars and address books with other people, or publish a public calendar as a link or embed on a website.
- Team accounts
- Create a team for a company or department, invite members, assign roles and control who can see which contacts, calendars and tasks.
- Free-busy scheduling
- Free-busy lookups show who is available when planning a meeting, and delegation lets an assistant manage your schedule. These need a compatible calendar app, not the web app.
- Developer API
- The API is built on CardDAV, CalDAV, vCard and iCalendar and covers what the web app can do. fruux also maintains the open-source sabre/dav server.
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.

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
