I Built an AI Health Coach That Actually Knows Me

Every health app wants to coach you, but none of them know you. They do not know your baseline. They do not know that your blood pressure spikes after certain meals, or that your ketones tank when you are stressed. They offer generic advice based on population averages and call it personalized.

So I built my own. It runs on my infrastructure, stores everything in a time-series database I control, and uses Claude to understand what I am eating, estimate the macros, and give me context on every measurement I log. Not generic advice. Insights based on my data.
