Get Rich or Die Smoking

Android rating: Free

This app has a catchy title going for it, and a lot more. It goes further than just showing you how much money you save by not buying cigarettes. It also shows you what you can now buy with that money instead! You can chart your progress and choose to reward yourself with trophies. You still get to see the health progress you’re making, and if you were to give in to a craving, there’s a relapse button to hold you accountable.
