Objective: To assess the expectations and satisfaction for using the “Thai Rai Kwan” smoking cessation smartphone application (TRK-App) and to evaluate its effectiveness in encouraging people to quit smoking.

Materials and Methods: The present was cross-sectional descriptive study. The participants included 112 smokers, 18 years or older who smoked at least five cigarettes a day and had installed the TRK-App in their mobile phone. Data were collected through self-reported questionnaires answered between March and June 2018.

Results: The participants had highest expectations for provision by the TRK-App of adequate smoking cessation information (mean 4.57; SD 0.56) and ease of first-time use (mean 4.51; SD 0.52). Afterwards, the participants’ satisfaction was highest for ease of first-time use (mean 4.53; SD 0.51), but lowest for smooth running of the TRK-App. In terms of success in quitting smoking, the seven days point-prevalence abstinence rate at a one-month follow-up was 21.4%.

Conclusion: The TRK-App provided positive results and enabled smokers to quit smoking.
