Instead of asking how many cigarettes are in a pack and how much you pay per pack, it asks you how much you pay per cigarette. Let’s be honest, most people need a calculator to figure that out. Also, it won’t let you enter a number below 18 for age that you started smoking. The majority of people I know that smoked started before age 18, so this isn’t helpful. I’m 2 days without smoking on 3/24/19, and it says I’m 50% through my nicotine withdrawal. However, it says that will last until 5/15/20.
