Review Article


There is a paucity of literature that has evaluated the information quality of the current bariatric and obesity applications. Our objective was to evaluate the quality of currently available smartphone applications for bariatric-patient care using the Silberg scale. The two most widely used smartphone application online stores were searched in June 2014 and a total of 39 applications were evaluated. The average Silberg score of the 39 applications was 4.0 ± 1.76. The current gaps of information quality include the lack of provision of appropriate references, full disclosure of sponsorship, and accurate disclosure whether the application has been modified in the past month.
