Track what matters. Burn what doesn't.
An open-source metabolic health tracker built for the intermittent fasting, biohacking, and fat-loss community. No subscriptions. No ads. No fluff — just clean data and honest progress.
Dashboard · Progress Charts · Phase Tracking · Red Flag Alerts
(screenshots coming soon — contributors welcome!)
