CalendarSync is an Android app which allows it to synchronize your appointments using CalDAV, FTP, HTTP, WebCal calendar feeds, 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.

You can get the app directly from me or from the Google Play Store. Here and also at the Google Play Store you can load the full and the free thest version of the app. The free test version can be used for two weeks without any limitations.
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 (using PayPal or a classic bank transfer). For more informations contact me at email@example.com.
