fruux

fruux is a cross-platform contacts, calendar and task service that keeps personal and team information synchronized across devices. It addresses the problem of maintaining consistent address books, schedules and to-do lists when people use different operating systems and applications, while also providing shared access for teams and automatic backups.

Core capabilities include contact search and sorting, calendar views with customizable week starts and 12/24-hour formats, and task lists with search and filtering. Collaboration features cover shared calendars, public calendars that can be linked or embedded, team creation with role-based access, free-busy scheduling, meeting attendance visibility, out-of-office access and delegation. The service supports Windows, Apple, Linux, Android, BlackBerry, Sailfish and a web app, and uses CardDAV and CalDAV for interoperability. Data is encrypted in transit and at rest, backed up automatically, and hosted on servers in Germany.

fruux is aimed at individuals, teams and organizations that need shared scheduling and contact management across mixed devices. Pricing is organized around a free Basic plan for personal use, a Pro plan with unlimited shares and support for up to 10 devices, and a Team plan that includes five members with additional members available on a per-member basis. All plans include automatic updates, backups, SSL encryption, unlimited contacts, calendars, tasks and storage.
