Version 1.2 of Countdown Widget is now on the Android Market. This version adds an option in the configuration screen to change the display format of the countdown timer.
Options include:
DDD:HH:MM:SS (this is the default, and was the original display format)
I have just published a new widget on the Android market: Timer Widget. This is very similar in functionality to the Countdown Widget, but it counts down a specific time frame instead of a specific date/time. It works just like a kitchen timer!
