Q: Looking for a Day Counter?

Hey, Recently i was trying 'Things' as a 2do List. the application is good, and i'm willing to pay for good apps, but its not worth 50$ in my opinion. anyhow my most Favorite thing about this app is that its let you know how many days you got left till the deadline comes.

is anyone familiar to a similar application, one that have Day Countdown for etch task, an if so i prefer an ical add-on. i search for months and still didn't find anything.
