It includes a calendar to set a quit date, financial goals by date, and reminders; the ability to track daily smoking habits with a log; and graphic features that track the money saved and the number of packs users haven't smoked since using the app. The app also provides health milestone alerts and craving tips, as well as Facebook and Twitter integration. With the video diary feature, users can even receive personalized video messages from friends and family. The app is available as a free download in iTunes.
