Summary

Apps are constant companions in all areas of daily life. A large number of apps cover health related questions and obesity related apps are also abundant. However, it is no easy task for users to identify appropriate apps. For the decision, users often employ information that is easy to access and interpret, such as the average star ratings provided for almost any app. However, the app stores from which the apps can be downloaded operate on an international level and only few manufacturers restrict access based on geographic region or other criteria. Thus, the specified average rating is probably rather a representation of the opinion of an international audience, but whether they adequately represent regional particularities or needs is questionable. With a specific focus on apps targeting obesity related topics, the aim of this paper was therefore to determine whether the average star ratings shown for most apps adequately represent opinions voiced by German-speaking users and whether they can therefore make a valid contribution to the opinion forming process.
