ASSESSING THE LANDSCAPE OF DIET-RELATED MHEALTH APPS: QUALITY, FEATURES AND USER PERSPECTIVES

This quantitative content analysis study evaluated the content, features, and quality of commercial diet apps in Asian marketplaces. Inclusion criteria encompassed both free and paid English-language apps for general dietary information. Apps that were disease-specific or redundant were excluded. App descriptions were extracted and evaluated by two independent research dietitians using a 100-point rubric based on predefined variables (e.g., language options, credibility, food databases, valuable features, health-behavior theory and technical quality). Good inter-rater reliability was achieved (kappa = 0.726; intraclass correlation coefficient = 0.763).
