Quitter

Smoking and fitness, of course, don't mix. The free Quitter app for iPhone keeps track of the number of days you have not smoked a cigarette, along with the amount of money you've saved by removing cigarettes from your budget.

Note: This link takes you to the vendor's site. From there, you can follow the link to the iTunes App Store, where you can download the latest version of the software.
