One thing I’ve always wished that the iPhone had was a more sophisticated countdown timer. While you can certainly use the iPhone’s Clock app to accomplish this in terms of hours or minutes, it would be more useful if you could add days to the mix as this would make it easier to count down to Birthdays and other important dates.
While Apple has yet to introduce an official solution, a newly released and free jailbreak tweak dubbed Counted by iOS developer Dave van Wijk introduces an elegant and fully customizable day counter to any iOS handset’s Lock screen.
