The challenging family and work environments affect health of women as well as their pregnancies in developing countries like India. Some of these pregnancies occur too early and may lead to health complications at the time of child birth. A preterm birth of infants is a significant public health issue and there are several problems faced by mothers and their families. These problems include absence of messaging / calling service in emergency, lack of communication channel with physicians, no platform for experience sharing, poor understanding about infant growth tracking, induced mental stress and shattered confidence. This paper discusses about a paper prototype design of proposed app for mothers of preterm infants. A paper prototype for this app is designed based on correlated literature survey as well as peer Android app review. This prototype design include several facilities for 'Save Our Souls' (SOS), user guide, growth tracking, experience sharing and mother's health monitoring, improving their work engagement and communication with assigned physician(s). In future, this app will provide a user guide in local Indian languages along with experience sharing option for mothers.
