"DID I BREAK MY FAST?" AI ASSISTANT
Unsure if oat milk in coffee, a diet soda, or sugar-free gum broke your fast? Just type it in. The AI analyzes its metabolic impact based on your exact fasting hour and goal (Weight Loss vs. Autophagy) and returns a clear verdict — Intact, Impacted, or Broken — with a breakdown of insulin, fat burn, and autophagy effects plus one-tap timer actions.
HOUR-BY-HOUR AI COACHING
• Precision insights for the exact hour of your fast
• Customizable AI Coach persona — choose the name and tone (Supportive or Strict/Science)
• Dietary filtering: Omnivore, Vegetarian, Vegan, Keto, Paleo, Carnivore, Pescatarian, Sardine Fast
• Meal Sequencing — an optimal eating order (vegetables, then protein and fats, then carbs) to blunt glucose spikes
• Contextual interventions: electrolyte tips, walk prompts, recovery nudges from wearable data
METABOLIC WAVE (GLUCOSE SIMULATION)
A real-time graph estimating blood glucose response from fasting duration and nutritional intake, mathematically aligned to a 98 mg/dL baseline. Visualize the estimated impact of every meal and every hour of your fast.

IMPORTANT DISCLAIMER
ChronoFast AI is an educational and wellness tool, not a medical device. AI insights and the Metabolic Wave are estimates, not measured from your blood. Always consult a healthcare professional before starting any fasting regimen — especially if you have underlying conditions, diabetes, or are pregnant or nursing. You must be at least 16 years of age to use this app.
