Diet was known for many years to play a key role as a risk factor for chronic diseases especially for elderly. The capability to interact effectively on health information application among elderly is becoming essential. A mobile technology can monitor diet and lifestyle of the elderly. We developed Nutrihealth application that comprises information on Body Mass Index (BMI), suggested menus, and calories intake. Persuasive techniques were implemented in the design of Nutrihealth mobile apps, to increase user engagement and behaviour change in healthy diet. The work starts with an initial study to select suitable persuasive techniques for elderly. The aim of this work is to evaluate the mobile application that implements a persuasive design. A technology acceptance model named Unified Theory of Acceptance and Use of Technology (UTAUT) has been used in the evaluation phase. Nine (9) elderly participants take part in the in-depth usage study in which they were asked to use the mobile apps for 3-days. The findings show majority of participants (90%) gave positive opinion on the design of the persuasive mobile apps. There is also an improvement in their calories intake during the 3-days study.
