Smokiary is a smoking-diary app, which users can easily check and track their spending and the amount of smoking. Research has discovered that many smokers don't care much about their health, but spending on cigarettes. However, it is still hard to know exactly how much they spend on cigarettes for themselves unless they record each time they smoke. Smokiary helps to solve the problem. With a simple user interface, they can easily track their spending on cigarettes, and it leads them to quit smoking.
