CalendarSync is an Android app which allows it to synchronize your appointments using CalDAV, FTP, HTTP, WebDAV or plain ics files (stored on your device or e.g. mail attachments). There are also a lot of additional features available. A list of the available features can be found on the "Manual". All this can also be done independent from the Google services like the Google calendar.

If you want to test features which require a license (e.g. the "Load from the web" option) you can get a free test license. You also can buy a full license.
The app is also available at the Google Market/Play Store, but google takes 30% of every transaction therefore it is more cost effective for you to buy the license from me directly. For more informations contact me at calendarsync[at]gmx.at.
