Maternal health is an important thing to care as a mother. Usually, mothers prioritize their physical health during pregnancy and tend to less prioritize herself after delivering baby. This article aims to find important issues on both during and after pregnancy related to maternal health. Those issues later will be developed into an app. Several issues that emerged are (1) pre-eclampsia and its impact to both mother and fetus or baby, (2) postpartum maternal health, and (3) mental health of the mothers (e.g., baby blues, post-partum depression). A questionnaire was composed and answered by 284 anonymous mothers who at least experienced pregnancy once. The results are nine functionalities that are expected by mothers to be implemented in a mobile app. Those nine are information about pre-eclampsia long-term (instead of short-term impact), how to prevent pre-eclampsia risk with easy procedures in daily life during pregnancy, automated decision system to early screening of pre-eclampsia, personalization of postpartum advice based on mothers current condition, feature that manage mother's mental condition, step-by-step postpartum exercises, automated decision system to screen PPD for both parents (not only mothers), feature that may reduce PPD symptoms based on their preferences, and multi-modal depression detection.
