Germanyfruux is a calendar service from Germany. It keeps calendars in sync between your devices over CalDAV, the open standard supported by Apple, Android and desktop calendar clients, and the CalDAV server behind the service is open source.
The company is German, so fruux is a European alternative for calendar sync, although the service itself is hosted on AWS rather than on European infrastructure. It suits individuals and small teams that want standards based sync without tying their calendar to one ecosystem.
