Summary

This trial tests whether a smartphone app and smartwatch can help Chinese, Malay, and Indian adults in Singapore improve their physical activity, sleep, and diet. Participants receive personalized digital nudges and complete surveys over 12 months. The goal is to see if these tools can boost cardiometabolic health and support healthy aging.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
a digital lifestyle intervention delivered via smartphone app and smartwatch, targeting physical activity, sleep, and diet
What this could lead to
If successful, this approach could offer a scalable, personalized way to improve heart health and prevent diabetes in Asian populations.
What could go wrong
This is an early-phase optimization trial, not a final test of effectiveness. The interventions are still being refined, and results may not apply to other groups.
