BUMP2.0 Feasibility Study

Participants in the experimental group will have access to the BUMP app, which aims to support them to control the amount and rate of weight gain during pregnancy, from baseline (early or mid-pregnancy) until they give birth. The app will prompt participants to regularly self-monitor their weight gain during pregnancy, and will provide access to a weight gain chart for tracking. Participants will receive feedback notifications about their weight gain trajectory, and will have access to information and tips on weight management during pregnancy.
