This study presents an AI driven platform for digital algorithmic nudging, designed to shape health behaviors of large populations. The platform uses a Graph-Neural Network based Recommendation System and health behavior data from wearable devices. A 12-week trial with 84,764 individuals in Singapore showed that AI optimized daily nudges increased daily physical activity and weekly minutes of Moderate to Vigorous Physical Activity (MVPA). The nudges were well received, indicating significant improvement in population level engagement metrics.
