In addition, mixed-method research was conducted in 2018 to evaluate this application. In 2019, this application will be examined its cost-effectiveness so that it can strengthen the advocacy process to the government to help the government consider effective budget allocation in 2020 and beyond.Please note: This application is intended for parents of children who have been registered by iPosyandu cadres.
