Best for syncing calendars and contacts over CalDAV
fruux syncs contacts, calendars and tasks across devices through CalDAV and CardDAV, with a free plan and Pro at €4 a month. It publishes no apps of its own and relies on each device's built-in clients, the free plan stops at 2 devices and 2 shares, and prices are in euros only.
Who fruux is for
- Fits if you want calendars and contacts in sync across phone and laptop
- Works for small teams that need shared address books
Who fruux is not for
- Tight if you stay free: Basic stops at 2 devices and 2 shares

- Watch out: prices are in euros, with no US dollar price
Why fruux gets a 2.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- BValue for moneyPro is €4 a month or €40 a year, under the category's $4.99 cheapest quarter. Team is €20 a month for 5 members.
- BFree plan and trialBasic is free with unlimited contacts, calendars, tasks and storage, limited to 2 devices and 2 shares.
- CFeaturesIt 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.
- CEase of useNo store rating on record. You set up accounts on each device through its own sync settings.
- APlatforms and integrationsWeb, Mac, Windows, Linux, iOS and Android through standard clients, plus Thunderbird, Fantastical, BusyCal and Outlook, and a developer API.

Keep fruux, or make your own?
Keep it
The plain part of fruux you could make: calendar and tasks. What surrounds it you could not. The 3 things listed below take a company, not a weekend.
It costs $44.69 a year.
What you could make
- Calendar and tasks: an app builder makes these well.
What you could not
- Apps for macOS, Windows, Linux, iOS and Android that stay in step with each other.
- It plugs into other products, Thunderbird, BusyCal and Fantastical among them, and has an API.
- Sharing with other people, which means accounts and invitations.
What this rests on. fruux’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is fruux?
fruux is a hosted service that stores contacts, calendars and tasks and syncs them to the devices and apps you already use through the open CardDAV and CalDAV standards. It also has a web app, shared calendars, public calendar links and team accounts. A free Basic plan allows two devices and two shares.
Worth knowing
- 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.
Key features
- 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.
