ownCloud – Open Source Web App For Managing Files, Contacts, Calendar & More..
There is a "getting stronger" opinion and movement on web users having their own self-controlled, free and open source clouds where data belongs to the users, can be transferred easily and privacy is not an issue.
ownCloud is supporting this movement with a cool app which works as a:
- file manager/explorer with share option, WebDAV support, the ability to play music files
- contacts manager
- and has planned features like image gallery, online text editor, online task manager, encryption, bookmarks, desktop sync client, Android&webOS apps and server-server sync.
It is built with PHP-MySQL (or SQLite) and is definitely a good option for users willing to move their data to the web + manage easily.
