After learning your schedule for 24 hours quit easier uses your desired quit date to determine how many fewer cigarettes you should smoke each day to achieve your goal. It them spreads out your time between each cigarette (based on your schedule) to help you slowly adjust to smoking less often.
Since QuitEasy learns and constantly adjusts to your schedule, it works for everybody, not matter how irregular your smoking habits are.
QuitEasy saves all smoking and schedule data on your phone and never uploads your data to the cloud. The only anonymous data collected by QuitEasy are crash results and usage data.
