A gap exists in applying structured System Development Life Cycle (SDLC) frameworks to community-facing mHealth platforms with embedded technology acceptance evaluation. This study presents the design, architecture, and iterative development of the \u201cSmart Daily Life Care\u201d cross-platform mobile application using a six-phase SDLC framework, targeting rural elderly communities in Thailand. The system architecture employed a microservices design with age-friendly UI engineering, conforming to WCAG 2.1 AA. Technology acceptance was evaluated post-deployment using the Technology Acceptance Model (TAM) with 200 participants (elderly users, caregivers, and health personnel). System efficiency was rated at x\u00af = 4.58 and user satisfaction at x\u00af = 4.64. TAM regression identified perceived usefulness as the dominant predictor of behavioral intention (\u03b2 = 0.412), followed by perceived ease of use (\u03b2 = 0.318) and social influence (\u03b2 = 0.268), with R2 = 0.682. Integrating TAM evaluation within SDLC phases enables iterative remediation of acceptance barriers before deployment. Village Health Volunteer networks function as indispensable sociotechnical enablers of adoption. The SDLC\u2013TAM integration provides a structured methodological approach suitable for replication in age-sensitive health information systems in low-resource settings.<\/jats:p>","DOI":"10.3390\/informatics13060087","type":"journal-article","created":{"date-parts":[[2026,6,18]],"date-time":"2026-06-18T00:49:42Z","timestamp":1781743782000},"page":"87","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Designing and Evaluating an mHealth Application for Rural Elderly Care Using a Structured Development Framework and Technology Acceptance Evaluation: Evidence from Thailand"],"prefix":"10.3390","volume":"13","author":[{"given":"Varit","family":"Kankaew","sequence":"first","affiliation":[{"name":"Department of Digital Technology, Rajamangala University of Technology Suvarnabhumi, Ayutthaya 13000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amnaj","family":"Sookjam","sequence":"additional","affiliation":[{"name":"Department of Health Science, Rajamangala University of Technology Suvarnabhumi, Ayutthaya 13000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aekarin","family":"Panpuk","sequence":"additional","affiliation":[{"name":"Department of Health Science, Rajamangala University of Technology Suvarnabhumi, Ayutthaya 13000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pratueng","family":"Vongtong","sequence":"additional","affiliation":[{"name":"Department of Digital Technology, Rajamangala University of Technology Suvarnabhumi, Ayutthaya 13000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wannaporn","family":"Suthon","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Rajamangala University of Technology Suvarnabhumi, Ayutthaya 13000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuwadee","family":"Chomdang","sequence":"additional","affiliation":[{"name":"Department of Digital Technology, Rajamangala University of Technology Suvarnabhumi, Ayutthaya 13000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sangtong","family":"Boonying","sequence":"additional","affiliation":[{"name":"Department of Digital Innovation Management Science, Rajamangala University of Technology Suvarnabhumi, Ayutthaya 13000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-6737-9297","authenticated-orcid":false,"given":"Anek","family":"Putthidech","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Rajamangala University of Technology Suvarnabhumi, Ayutthaya 13000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Olla, P., and Tan, J.
