Fjörbók
Your book of vitality.
Tell your AI assistant what you ate, how you feel, or what the doctor said — Fjörbók keeps the record and shows your trends, so you can build and protect your own vitality.
Log by talking
Tell your AI assistant “chicken burrito bowl, about 700 calories” — it estimates the rest and files it. No barcode scanning, no database to search.
Trends, not noise
Fjörbók watches the weekly arc of your calories, protein, alcohol, and weight — so you see what’s actually happening, not daily scale jitter.
A memory of your health
Log conditions, medications, symptoms, and what each doctor tells you. Fjörbók keeps a health history you actually hold onto — not scattered across apps, portals, and memory.
Carry it to any doctor, in any language
Because your record lives with your AI assistant, you — or a doctor — can just ask and get the whole picture. Even in a foreign clinic, your assistant can explain your health in their language.
What “Fjörbók” means
Fjörbók (FYUR-bohk) joins two Old Norse words: fjör, the life force — the vigor that carries a body through hard winters — and bók, a book, where things worth keeping are recorded. It’s the book of vitality: a record of what fuels you, so you can build your own strength, one meal at a time.
