Tracking data is never going to help anyone quit. A person has to want to quit badly enough, and even then they need help sometimes like patches or nicotine gum. Data may be nice for scientists but it's useless for individuals. I am lucky - I have very strong willpower. When I decided to quit (a very long time ago) I just did it. It definitely wasn't easy but I am an incredibly stubborn person. I will not let anything or anyone beat me.
