Important notes
It does not measure glucose or blood sugar. It's a signal of autonomic tone, for informational purposes.
A wellness and screening tool, not a medical diagnostic device. It does not replace evaluation by a professional.
Orienting signals of sleep wellness, not a diagnosis of sleep disorders.
A tool for self-awareness and wellbeing, not an instrument for clinical diagnosis.
Kokaru organizes and guides your health information; it does not make diagnoses or replace a professional's evaluation.
Reference wellness information; it guides, it does not diagnose or replace a professional's evaluation.
