My Baby's Movements: An assessment of the effectiveness of the My Baby's Movements phone program in reducing late-gestation stillbirth rates.

The MBM app had low uptake and its use was not associated with stillbirth rates but was associated with some neonatal benefit, and higher rates of IOL and early term birth. Use and acceptability of tools designed to promote fetal movement awareness is an important knowledge gap. The implications of increased IOL and early term births warrant consideration in future studies.
