There are a few other apps out there which motivate staying quit by the same principles - showing progress toward health improvements and recovery and also accumulating savings from not smoking. I find this to be the best, with an excellent interface, more detailed breakdown of health improvements, % recovery progress on each item and time remaining until 100% is reached, also for how long you have been at 100% recovery. Critically, there are several health items in the few days, first week, and month. Most of the major ones, like reduction in lung cancer risk to that of a non smoker take as long as 10 years to reach, but this I expect will be an excellent reinforcement to not have "just one" after 6-12 months of abstinence. That seems to be my problem and the "just one" becomes "just one more" a few days later, then again, until some emotional or work stress event happens and my resolve fails completely. A look at this app, seeing the progress meters moving forward and the savings racking up, might just stop the very first "just one" from ever happening. You can also use this app even if you arent quitting yet or are having trouble staying committed to quitting. Just set your quit date and give quitting a good try. If you fail and take a few days before getting ready to give it another try, look at the health and savings progress you would have reached by the time you are going to try again. This is actually how I got past my first few false starts.
My one complaint is that there seems to be no way to "claim" one of your targets or reward gifts (things you can buy with your savings, user setable) and have the money deducted equally or proportionally from all other targets. That would be a great new feature.
