The elderly population in Malaysia was 6.6% in 2000, while the estimated number of elderly in 2025 increased to 13.4%. This figure will continue to grow by 20.8% by 2050. This increase requires healthier senior citizens to face the new millennium. The development of information and technology can improve the quality of life of older adults. Many technologies, such as health-based technology, can be used for older adults. Identifying the user experience (UX) components and effectiveness of older adults' health-based applications is essential to studying the effects of healthy ageing. This study was conducted to resolve questions and objectives regarding the importance of user experience for older adults and to identify the effectiveness of health-based applications. A research gap that needs to be studied is the evaluation of the improvement of guidelines for the provision of health application items for the sake of user experience. The case study method was used to explore the use of the health application developed named WESIHAT3.0. The WESIHAT3.0 mobile application is a prototype developed based on education and healthy eating for older adults. The research uses qualitative and quantitative methods, including user diaries, questionnaires and interviews. We used the user experience question (UEQ) to obtain feedback from the older adult's user experience component and the focused interview method in the case study. Respondents were selected from the Older Adults Activity Center (PAWE) in the Bandar Tun Razak area through a purposive sampling technique. The study's results found that the user experience component scale on the WESIHAT3.0 health prototype has an attractiveness value of 1.73, a pragmatic quality of 1.48, and a hedonic quality of 1.24. Improvements to the WESIHAT3.0 prototype have also been identified to add information on calories and nutritional intake by age. In conclusion, it is important to develop new technologies that can aid older adults in healthy ageing, while simultaneously ensuring that these technologies contribute positively to the digital era.
