A sample of 176 individuals including the elderly in Chamai district, general public, and IT specialists participated in this study. The data were gathered through in-depth interviews, online questionnaires and documents. Content analysis was conducted for qualitative data, while frequency, percentage, mean, and standard deviation were used for quantitative data analysis. The results indicated that the mobile application can be used to assess nutritional status of the elderly and guide their dietary intake. It is practical and easy to use.
