A gap remains in technology-driven personalized support tailored to caregivers\u2019 needs.<\/jats:p>\n <\/jats:sec>\n \n Objective<\/jats:title>\n This study aimed to develop a theory-driven, multicomponent mobile app specifically designed for caregivers of individuals with dementia and test its usability among end users.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n \n We developed\n CareBuddy<\/jats:italic>\n , a mobile care ecosystem based on the stress process model and user-centered design. The app includes personalized assessments and tailored solutions, an artificial intelligence\u2013driven chatbot, GPS-based location monitoring, peer support, a helpline, telemedicine, health care provider integration, and caregiver self-care resources. Development was informed by interviews with caregivers and stakeholders, followed by a 2-phase pilot test involving 18 and 10 participants, respectively, to assess usability and acceptability.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n In phase 1, the mean system usability scores increased from 65.4 (SD 11.8) in round 1 to 73.8 (SD 15.9) in round 3, exceeding the benchmark of 68. In phase 2, caregivers rated the app highly, with an overall mean score of 95.4 (SD 8.5) on the Mobile Health App Usability Questionnaire. The domains of ease of use (mean 24.1, SD 2.9), user interface and satisfaction (mean 40.3, SD 3.4), and usefulness (mean 31, SD 3.9) received high Mobile Health App Usability Questionnaire ratings. Participants valued the content focused on dementia management and caregiver well-being. Caregivers appreciated the interactive features: social networking portal, service directory, and conversational large language model. Feedback highlighted areas for improvement, including reducing textual overload and addressing navigational challenges.<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n CareBuddy<\/jats:italic>\n offers a multifaceted digital solution for dementia caregivers, with high usability and satisfaction. An ongoing trial is evaluating the app\u2019s effectiveness in improving caregiver outcomes.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.2196\/78759","type":"journal-article","created":{"date-parts":[[2025,11,3]],"date-time":"2025-11-03T18:00:09Z","timestamp":1762192809000},"page":"e78759-e78759","source":"Crossref","is-referenced-by-count":5,"title":["Supporting Dementia Caregiving With a Mobile Care Ecosystem: Development and Mixed Methods Study"],"prefix":"10.2196","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5380-0525","authenticated-orcid":false,"given":"Chetna","family":"Malhotra","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9338-9347","authenticated-orcid":false,"given":"Yanzhen","family":"Yue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-4623-0357","authenticated-orcid":false,"given":"Chandrika","family":"Ramakrishnan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0991-5138","authenticated-orcid":false,"given":"Shimoni","family":"Shah","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6827-9226","authenticated-orcid":false,"given":"Wenda","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9465-5937","authenticated-orcid":false,"given":"Philip","family":"Yap","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7591-1699","authenticated-orcid":false,"given":"Chin Yee","family":"Cheong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1720-4718","authenticated-orcid":false,"given":"Irene","family":"Teo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7853-4112","authenticated-orcid":false,"given":"Shiou-Liang","family":"Wee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3532-5764","authenticated-orcid":false,"given":"Xiangming","family":"Lan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9855-3652","authenticated-orcid":false,"given":"Yi","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1169-2121","authenticated-orcid":false,"given":"Chee Seng","family":"Chong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7027-8476","authenticated-orcid":false,"given":"Xueying","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-8564-541X","authenticated-orcid":false,"given":"Ivy","family":"Chua","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1010","published-online":{"date-parts":[[2025,12,30]]},"reference":[{"issue":"2","key":"R1","doi-asserted-by":"publisher","first-page":"e105","DOI":"10.1016\/S2468-2667(21)00249-8","article-title":"Estimation of the global prevalence of dementia in 2019 and forecasted prevalence in 2050: an analysis for the Global Burden of Disease Study 2019","volume":"7","author":"Nichols","journal-title":"Lancet Public Health"},{"key":"R2","unstructured":"Dementia.
