Do you use Smokeless Tobacco?
iQuit Smokeless is a simple app that lets you document every new can you open with 1 touch of a button. After a few weeks have passed you can look back and see how much you have actually used. You can "Check in" in between cans and see how youre doing. By doing this you can stretch out the time between opening new cans. Maybe you can even decide you can QUIT! There are no ads or anything begging you to upgrade here. Just a simple app that may help. Its my gift to you.
