The intervention was a mobile app encouraging weekly self\u2010weighing and gestational weight gain tracking, offering feedback relative to Institute of Medicine (IOM) recommendations and signposting to online resources. The control group received usual antenatal care. Feasibility outcomes assessed retention and app engagement. Weight change and the proportion exceeding the IOM\u2010recommended upper weekly weight gain rate were also assessed.
