Caffeine timing for sharper days

Connections
Caffeinator estimates active caffeine from your selected drinks, absorption timing, and caffeine half-life, then blends that with a simple daily energy curve and post-meal drowsiness model to suggest when to drink next. It is a lightweight planning toy, not medical advice. Logic co-generated and cross-verified by Gemini Flash 3.5, GPT-5.5, and Claude Sonnet 4.6.
