Abstract Background: Frailty increases vulnerability to functional decline, hospitalization, and poor quality of life in older adults. Digital health interventions (DHIs), like mobile applications, wearable devices, and telehealth, show promise in promoting physical activity, self-management, and healthy aging. Thus, the purpose of this study is to thoroughly examine how well digital health treatments can stop or slow the evolution of frailty in older adults who live in the community. Methodology: This research was carried out in compliance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The eligible studies published between January 2015 and July 2025 were included in the study. Participants were community-dwelling older adults (≥60 years) with frailty or at risk of frailty. DHIs (telehealth, mobile health mHealth, wearable devices, remote monitoring, and online platforms) were compared with usual care or nondigital approaches. Since interventions and outcome measures varied, data were extracted using a standardized form, their quality was evaluated using the proper risk of bias techniques, and then narratively synthesized. Results: In this review, seven studies with a total of 1167 participants were included, comprising one observational descriptive study and two cross-sectional studies. DHIs, including wearable sensors, accelerometers, and mHealth programs, proved feasible and effective for frailty assessment and management, showing high adherence, accurate frailty detection, and improvements in mobility and physical activity. Overall, digital tools hold strong potential for objective frailty monitoring and healthy aging promotion. Conclusion: DHIs such as wearable sensors and mobile applications are feasible and effective for monitoring, detecting, and managing frailty in older adults. They offer objective, noninvasive tools to support early detection, promote physical activity, and enhance geriatric care.
