Alundus (http://www.alundus.com) has announced Calendar Buddy app for the Mac, iPhone and iPad. The app lets you automatically add calendar entries into your calendar and have them automatically update.
Calendar Buddy adds the events automatically to your calendar with one touch of the button. And it keeps them updated throughout the year with updated times and schedule changes without doing any additional work.
The app currently includes the following calendar categories (more to come soon): Academic Calendars; Business Calendars; Entertainment Calendars; Holiday Calendars; International Calendars; International Holiday Calendars; Miscellaneous Calendars; Music Calendars; and Religion Calendars. All you have to do is find what calendar you want to add and click that calendar; it will then add and automatically sync that calendar to your device
Calendar Buddy for the Mac requires Mac OS X 10.6 or higher and is available at the Mac App Store. Calendar Buddy for the iPhone, iPod touch, and iPad requires iOS 3.2.1 or later and is available in the Apple App Store. Both versions are US$0.99 each.
