Boston, Massachusetts - App Diner today is pleased to introduce MyCountdown for iOS, their app that creates countdowns to all upcoming special events and occasions, such as holidays, birthdays, and anniversaries. Users can set each special event to countdown in years, months, weeks, days, hours, minutes, and even seconds. Beyond simply creating the event, MyCountdown also allows users to upload their own pictures, via Photo Stream or built-in camera, for background and event photos, personalizing each event. Users can share completed events with friends via email, Twitter, or Facebook.
