How we grade them
| 3.6GPAGoogle CalendarExcellent | 3.2GPATuta CalendarVery good | |
|---|---|---|
| Value for money | BThe paid version only comes inside Google Workspace, from $7 a user a month on a 1-year commitment. That's about typical, and Gmail, Drive and Meet come with it. But Starter adds nothing to the calendar itself. More booking pages and payments wait for Standard at $14. | ATuta's lowest paid personal plan is €3 a month paid yearly, €3.60 monthly, taxes included. That's under what most calendar apps charge, and it's Tuta's encrypted email, unlimited calendars and 20 GB of storage in one. The calendar isn't sold on its own. |
| Free plan and trial | AFree with a personal Google Account on web, Android and iPhone, with one appointment booking page thrown in. Most people will never pay. Extra booking pages, payments and automatic email reminders are the paid bits. | BThe Free plan gives you one encrypted calendar and 1 GB, with apps on every platform. But there's no calendar sharing, no event invitations and no offline support, so it's a calendar for you alone. Those limits are tight. |
| Features | AShared, colour-coded calendars you can view together, a booking page, Google Meet links and files on events, and Google Tasks next to them. Workspace plans add Gemini scheduling from Gmail and Time Insights, though Time Insights only shows on a computer. | BEnd-to-end encryption on events, invitations and shared calendars, with reminders kept hidden from your phone's operating system. On paid plans you can share with read or write rights. But the calendar page mentions no two-way sync with Google or Outlook, only import. |
| Ease of use | B4.5 from about 132,000 App Store ratings. If you have a Google Account there's nothing to set up. On Workspace plans, an event spotted in an email can be added with one click. | BIt's part of your Tuta account, so if you use Tuta Mail it's already there, and old calendars import in the settings. We have no App Store rating on record to go by, so it stops at a B. |
| Platforms and integrations | AWeb, Android and iPhone, tied into Gmail, Google Meet, Google Tasks and Stripe for paid bookings. No desktop app is listed, so on a computer it lives in a browser tab. | BIt runs on everything: web, 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. That keeps it at a B. |
| Best for | a free calendar for anyone with a Google Account | a calendar your provider can't read |

- Scheduling from Gmail with Gemini

- 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.

- 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.
