Worldwide the use of mobile phones among young people is dramatically increasing. Even in remote places, young people are using their phones not only as a way of communication but also to look for information. Because of this, IPPF ‘s Member Association in Bolivia has worked with young people to develop a sexual and reproductive health app to complement its routine services. We have also developed and are evaluating a contraceptive intervention delivered through the app to increase use and acceptability of effective contraception among young people. This session will cover the youth-centered design of the app and service delivery aspects of the project, as well as the experience of collaborating with researchers to ensure robust evidence generation. This session will be of interest to those working in inclusive technology projects, researchers, health and public health providers and implementers working in adolescent health and sexual and reproductive health.
