• Own or have access to a mobile phone or tablet with internet and text messaging capabilities or will be loaned an iPad mini for the study duration.
• Both men and women and those from non-ANAI racial/ethnic groups.

Alaska Tribal Health System stakeholders:

• Input from healthcare providers, cessation specialists, and THO leaders will be gathered to understand potential facilitators and barriers to adoption of the intervention within the ATHS. The ANTHC team will invite individuals to participate through phone and email communications.
