Consumer Technologies for Personalized Health: Feasibility of Five‐Compartment Body Composition Self‐Assessment Using Mobile Devices

Obesity (Silver Spring)Published Method comparison (validation) study

Authors' conclusion

Properly calibrated smartphones and smartwatches can yield multicompartment body composition estimates that closely match laboratory standards and support precise, low-cost monitoring in remote and resource-limited settings.
