Smartphone app interventions are promising yet rarely move beyond the research sphere. Rather than inventing stand\u2010alone apps that rarely come to scale, integrating health interventions into existing multifunction apps would be a paradigm shift for research and practice.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a prospective, single\u2010arm pilot study of an intervention platform built directly into Blued, a geosocial networking (dating) app for MSM with more than 6 million users in China. The intervention provided telePrEP care (including in\u2010app clinician services, reimbursed laboratory testing and mailed PrEP prescriptions), health messaging, and an order platform for home HIV tests and condoms. The pilot study, in Beijing and Chengdu, compared the intervention to contemporary repeated cross\u2010sectional comparison surveys. Primary outcomes were benchmarks for feasibility (\u226530% home HIV test orders and \u226520% HIV PrEP prescriptions) and acceptability (\u226571 System Usability Scale [SUS] score). Preliminary efficacy assessment compared changes in the intervention group to the repeated comparison groups with generalized estimating equations (GEE) models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>From July 2022 to December 2024, 423 people started the pilot intervention, 400 (95%) were retained at 6 months and 399 (94%) at 12 months. All primary outcomes at 12 months were significantly higher than prespecified benchmarks: 87% (366\/423) ordered HIV tests, 42% (176\/423) received PrEP prescriptions, and the mean SUS score was 73\/100. In GEE models adjusting for group characteristics and the secular trend of the comparison groups, between baseline and 12 months, the intervention group had an absolute increase in PrEP use of 20% (95% CI: 13%\u201327%) and in HIV testing of 7% (95% CI: 1%\u201313%). There was no difference in condom use.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In this study, we found that it is feasible and acceptable to incorporate HIV prevention interventions into existing apps.
