<![CDATA[Maternal morbidity and mortality can be prevented when women and their families recognize warning signs during pregnancy and seek health services promptly. This study aimed to analyze the effectiveness of Android-based education to improve knowledge and reduce anxiety in pregnant women related to pregnancy danger signs. This study was an experimental study with a one-group pretest and posttest design, involving 87 pregnant women at Andalas Health Center, Padang City, who were selected using a simple random sampling technique. Data on the level of knowledge and anxiety levels in the pre- and post-treatment phases were measured by filling out a questionnaire. Furthermore, a test of differences in knowledge levels between before and after treatment was carried out using a paired samples t-test; meanwhile, differences in anxiety levels between before and after treatment were tested using the Chi-square test. The results showed that the p-value for the paired samples t-test was 0.000, which means that there was a difference in knowledge levels between before and after treatment. The p-value for the Chi-square test was 0.004, which means that there was a difference in anxiety levels between before and after treatment. Based on these results, it could be concluded that Android-based education is effective in improving knowledge and reducing anxiety levels in pregnant women related to pregnancy danger signs.Keywords: pregnancy danger signs; education; Android; knowledge; anxiety ABSTRAK Morbiditas dan mortalitas pada ibu dapat dicegah ketika wanita dan keluarganya mengenali tanda-tanda peringatan selama kehamilan dan segera mencari layanan kesehatan.
