Background Nutrition apps are effective in changing eating behavior and diet-related health risk factors. However, while they may curb growing overweight obesity rates, widespread adoption is yet to be achieved. Hence, profound knowledge regarding factors motivating hindering (long-term) nutrition app use crucial for developing design guidelines aimed at supporting uptake prolonged of apps. Objective In this systematic review, we synthesized the literature on barriers facilitators across disciplines including empirical qualitative quantitative studies with current users, ex-users, nonusers Methods A search 6 databases (PubMed, Web Science, PsychINFO, PSYNDEX, PsycArticles, SPORTDiscus) as well backward forward citation was conducted. Search strategy, inclusion exclusion criteria, planned data extraction process were preregistered. All published German or English eligible if examined adolescents (aged 13-18) adults who either Based content analysis, extracted individual grouped into categories.

Conclusions The resulting conceptual underlines pronounced diversity reasons (not) using apps, indicating there no “one-size-fits-all” approach tailoring needs specific groups seems promising increasing engagement.
