Primary care physicians are in an excellent position to address smoking during routine consultations. To this end, physicians have assessment tools and brief interventions appropriate for the duration of consultations. However, these tools are difficult to use consistently in practice. Mobile applications (apps) aimed at stopping smoking could help solve this problem, provided they meet certain quality criteria. This article provides criteria for evaluating these apps to facilitate their identification and use by clinicians. Five French-speaking apps are described. If integrated into routine Primary Care, these apps could facilitate smoking cessation.
