In recent years, mobile apps have emerged as valuable tools for supporting self-management in chronic diseases such as diabetes, particularly for the nutritional aspects of the disease. However, the quality, accuracy, and adherence of these apps to established dietary guidelines remain underexplored and inconsistent.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n The study aims to evaluate the quality and adherence to guidelines of digital nutrition management apps for diabetes, with a focus on dietary guidelines from the American Diabetes Association (ADA), World Health Organization (WHO), European Association for the Study of Diabetes (EASD), and Diabetes Canada (DC).<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n A quality evaluation was performed, involving the identification of mobile apps from the Google Play Store and Apple App Store. A total of 24 apps were selected based on predefined inclusion and exclusion criteria. Apps were analyzed for their content and features using a compliance checklist derived from official dietary guidelines for diabetes, including carbohydrate tracking, meal planning, glycemic control, fiber intake, physical activity, weight management, and education about diabetes. Additionally, the Mobile App Rating Scale was used to evaluate app quality in terms of engagement, functionality, aesthetics, and information. Intraclass correlation coefficients were used to calculate interrater reliability. Pearson correlation coefficients were also calculated.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n Only 2 apps showed full compliance with the dietary guidelines, while most apps showed partial adherence. The Mobile App Rating Scale evaluation revealed significant variability in app quality, with mean total scores ranging from 9.46 to 17.69. This finding indicated major gaps in user engagement, functionality, educational content, and personalization. The intraclass correlation coefficient was 0.86, which indicates good interrater reliability, and the Pearson correlation coefficient was 0.88, suggesting good consistency between the authors.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Even with the growing availability of nutrition management apps for diabetes, many lack full compliance with dietary guidelines and show room for improvement in their content quality. Collaboration between health care professionals, developers, and patients is essential for the future development of these tools to effectively support diabetes self-management. Strengthening guideline adherence and content quality can increase the effectiveness of these digital tools in promoting self-management and improving health outcomes for individuals with diabetes.<\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/80890","type":"journal-article","created":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T07:50:06Z","timestamp":1777708206000},"page":"e80890-e80890","source":"Crossref","is-referenced-by-count":0,"title":["Quality and Guideline Adherence of Mobile Nutrition Management Apps for Diabetes: Evaluation Study"],"prefix":"10.2196","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-2371-588X","authenticated-orcid":false,"given":"Sidra","family":"Jahanzeb","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1813-8529","authenticated-orcid":false,"given":"Nadia","family":"Davoody","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2026,6,1]]},"reference":[{"key":"R1","unstructured":"Diabetes.
