Circadian Habit &
Metabolic Engine
Most apps force you into rigid schedules that fight your biology. VitalsFlow uses circadian physiology, autonomic recovery metrics, and adaptive metabolic science to front-load deep work and automate fuel tracking.
Engineered for Human Biology
Zero generic tracking. Everything is calibrated to your natural bio-rhythms.
Circadian Energy Wave
Dynamically tracks your 24h biological wave. Front-loads high-demand Deep Focus cognitive tasks into your natural morning Cortisol Awakening peak (09:30–12:00).
Smart Plate Scanner
Instant visual fuel breakdown with 2-tap culinary cooking oil calibration to prevent 250–400 kcal tracking drift from home gravies and stir-fries.
Dynamic TDEE & EWMA
An Exponentially Weighted Moving Average filter removes scale water and sodium noise to reveal true metabolic mass trends, adapting your expenditure weekly.
Autonomic Readiness Score
Composite morning readiness derived from HRV (rMSSD vagal tone), resting heart rate, and sleep architecture without subscription paywalls on your health data.
Compassionate Flex-Streaks
