AgeMeter measures key functional biomarkers of aging, such as memory and lung function. By comparing a test taker's scores to norms by age and sex, the AgeMeter estimates a person’s functional age, which may differ from chronological age. Healthcare practices that focus on aging and aging researchers can use the AgeMeter to confirm whether interventions actually cause a person to have the functional ability of a younger age. "For PGP, supercentenarian, aging reversal studies, and everyday wellness, we need cost-effective, standardized, quantitative insight into a diverse set of physiological measures. The AgeMeter can help us get there." - Dr. George Church, Harvard University Tested Biomarkers: • Auditory Reaction Time • Highest Audible Pitch • Lung Function: Forced Vital Capacity • Lung Function: Forced Expiratory Volume • Memory • Heart Rate Variability • Pulse Oxygen • Muscle Coordination • Muscle Movement Time • Vibrotactile Sensitivity • Decision Reaction Time • Decision Movement Time • Movement Speed An AgeMeter kit is required to use some of this app's features.
