Smartphone Phenotyping Review Synthesizes Cross-Condition Evidence

A scoping review published in Journal of Medical Internet Research (2026) synthesizes 65 peer-reviewed studies from 2012–2025 that use only onboard smartphone sensors to assess health across mental, physical, and substance-use domains. It finds most studies are observational with a median sample size of 52, frequent use of validated clinical scales (n=41), wide sensor heterogeneity, and recurring methodological gaps limiting reproducibility and clinical translation.
Scoring Rationale
Comprehensive cross-condition synthesis with clinical peer review; limited by observational studies and heterogeneous methods reducing reproducibility.
