Objective: To identify the availability and quality of apps supporting Dietary Approaches to Stop Hypertension (DASH) education. Methods: The researchers identified DASH apps over 1 month in the Apple App Store. Five registered dietitians used the App Quality Evaluation (AQEL) to evaluate app quality on 7 domains. Interrater reliability was tested using intraclass correlations. Results: One paid and 3 free DASH apps were evaluated. Interrater reliability (n = 5) was good for 3 apps and fair for 1 app. Only the paid app scored high (>8 of 10) on most AQEL quality domains. Conclusions and Implications: Based on lower quality found among the included free apps, further development of free apps is warranted. Whereas the paid app may be useful in supporting DASH education, future research should determine whether improvements in clinical outcomes are found and whether this app should be improved to address AQEL domains better.
