Fruux – Cross-Platform Synchronization

The address book and calendar you spent hours creating and then saved on your desktop computer might be really helpful when you’re sitting at home, but what happens when you need to access that information from work or when you’re sitting in a coffee shop? If your contact information is locked up inside a desktop computer, you’re out of luck.

Fruux offers a solution for anyone who is looking for ways to open up their calendars, contact books, and tasks lists. The web application is accessible from anywhere, on any device, and the calendars that you can create are completely shareable with friends and family. Sign up for a free account and start syncing the apps you already use on a regular basis. Fruux works with virtually any device and app that supports the open standards CardDAV and CalDAV. Fruux offers a streamlined way for you to update and edit the data that you use every day, like dates on the calendar or addresses in your contact book.

When you use fruux, you can work together on schedules and to-do list with the people you’ve selected. You can create a group address book that you share with your family and build a collective calendar to share with the parents in your child’s playgroup. You can even publish semi-private information, like work schedules, while remaining totally in control of the way that information is distributed. Fruux is an excellent tool for people who are looking for smarter ways to keep their data unified across multiple devices and platforms.
