The purpose of the usability and pilot testing for the project "Developing a Bi-national Buddy Intervention for Smoking Cessation and Cultural Education" is to better understand how users interact with the smoking cessation app, and to improve the product based on the results. In pilot testing the smoking cessation app the investigators will examine the feasibility of our approach. The usability testing portion of the study is intended primarily to improve on the design of the smoking cessation app, and will: gather quantitative data on participant's performance, identify usability problems, and determine user satisfaction with the app. The pilot testing portion of the study will evaluate the feasibility, time, cost and statistical variability in an attempt to predict an appropriate sample size and improve upon the study design prior to performance of a full-scale research study.
