this is a quit meter, which registers how much life you've saved, how much money you've saved, how many cigs you would have smoked etc. I found it incredibly useful when i gave up.
here are my stats from it, which i still have running on my desktop
6y 7m 2w 6d 17:14 smoke-free, 60,600 cigs not smoked, £15,150.00 saved, 6m 4w 10:00 life saved
But where is the fifteen grand I've saved???
