Background and aims Smartphone applications (apps) hold promise for delivering tobacco smoking cessation support to large numbers of people at low unit cost. Smoke Free is an evidence‐informed, widely used app that is highly rated by users. This study aims to assess its effectiveness compared with no support. Design Two‐arm individually randomized controlled effectiveness trial. Setting Online trial with no restrictions on location. Participants English‐speaking smokers aged ≥ 18 years willing to make a quit attempt within 4 weeks from initial contact ( n = 4990). Measurements The primary outcome measure is self‐reported 26‐week continuous smoking abstinence. Secondary outcome measures include quit attempts in the first 4 weeks post‐randomization, 12‐week continuous smoking abstinence and 26‐week continuous smoking abstinence among those who made a quit attempt. Comments If it is effective, the Smoke Free smartphone app is an affordable and widely implementable intervention to help smokers to quit.
