Physical activity (PA) data collected by mobile devices such as smart bands and smartphone apps have the potential be used screen in breast survivors. </sec> <title>OBJECTIVE</title> The aim of this study was assess collection rates terms PA data, investigate correlation between from distress-related questionnaires apps, demonstrate factors associated with <title>METHODS</title> In prospective observational study, patients who underwent surgery at Asan Medical Center, Seoul, Republic Korea, June 2017 March 2018 were enrolled asked use both a app band 6 months. overall compliance daily via walking wearable analyzed within-subject manner. longitudinal calculated examine dropout pattern. We also performed multivariate linear regression analysis collection. Finally, we tested count average steps level using Pearson analysis. <title>RESULTS</title> A total 160 female surgeries enrolled. 88.0% (24,224/27,513) 52.5% (14,431/27,513), respectively. rate 77.8% day 180, while rapidly decreased over time, reaching 17.5% 180. Subjects young, other comorbidities, or receiving antihormonal therapy targeted showed significantly higher app. However, no factor band. level, step counts significant level. <title>CONCLUSIONS</title> Smartphone are feasible tools collect on correlated participants’ which suggests role management <title>CLINICALTRIAL</title> ClinicalTrials.gov NCT03072966; https://clinicaltrials.gov/ct2/show/NCT03072966
