The goal of the MOMENTUM suite of awards is to holistically improve maternal, newborn, and child health and nutrition services, voluntary family planning, and reproductive health (MNCHN/FP/RH) in partner countries around the world. To that end, MOMENTUM uses innovative approaches, including the use of digital health tools, to enhance individuals’ health knowledge and care-seeking behaviors, with the goal of improving health outcomes. This brief summarizes findings about how MOMENTUM and its partners are using client-facing digital health tools. We examine the strategies and approaches to using these tools and their impact on access to health information and changes in care-seeking behaviors.
