Days2Go is a free iPhone application allowing you to countdown to any of your native calendar events.
Specifically written for iOS4, Days2Go displays all your future calendar events; showing Days, Hours, Minutes and Seconds until your event occurs.
Whats great is that Days2Go brings up events from your native calendar, you’re likely to have your favourite events, anniversaries, birthdays etc. in your calendar already, meaning they are displayed by Days2Go automatically.
Also, the cool thing about Days2Go is that you can star specific events from your calendar, to show a countdown to the most important dates, just in case you dont want a countdown to all of your day to day events of lesser importance.
Days2Go displays an icon badge showing the Days2Go until your next event without the need to launch the app.
