So many people have relapses and I am one of those. I wish there were a way to add a cigarette when you mess up and have it effect the dashboard totals. I've had to restart the app twice just for smoking one cigarette each time. I feel like ignoring my relapse would be lying but its such a hassle to change my quit date. If something like that were added this app would be perfect.
The diary in the new version (3.0, released a couple of weeks ago) asks how many cigarettes you smoked and takes those figures, including the money spent, from the totals on your dashboard.
Hopefully the app is perfect now
