Tannic has launched iDayZ for the iPhone and iPod touch. The app keeps track of birthdays and anniversaries in a user's contact list, listing upcoming events by age, name or event type; further details are provided by tapping on a given contact. Also present is a "celebrate" button for each contact, with a pop-up screen supporting e-mail and Amazon gift links.

Contact views display photos and event dates, as well as ages (birthdays) or years passed (anniversaries), where appropriate. More info is available on the birthday screen, which includes days left and trivia such as person's astrological sign, Chinese year, birthstone and flower. Anniversary screens show countdowns and gift suggestions. iDayZ is available at the App Store for $1.
