Eligibility Summary
The goal of this study is to compare the effectiveness of two smoking cessation programs to determine which better helps people change their smoking behavior, the control or the experimental intervention? Both interventions include access to a mHealth app and other publicly available stop-smoking resources. The two app versions each include best practice advice and guidance for quitting smoking, but one includes additional content designed for people who aren't ready to quit smoking. The investigators hypothesize that people who receive the experimental intervention will be more likely to request additional stop-smoking resources offered through the intervention and report smoking abstinence after 6 months. The investigators also hypothesize people assigned to the experimental app will have better app engagement and be more likely to report positive changes in their smoking behavior and use of other evidence-based stop smoking treatments that are publicly available.
