Your body has been leaving you notes for years. Start reading them.
A field notebook for noticing patterns between what you eat and how you feel. Note meals and symptoms in seconds; a statistical engine — on your phone, not on a server — finds patterns and always tells you how strong the evidence is.
Not a calorie counter. Not fitness. Not a community. It's a journal that thinks slowly.
It observes, correlates and prepares conversations with your doctor. It never diagnoses or treats — medical decisions still belong with your doctor.
Spanish first. Every word exists just as well in English.
agreement among providers reading the same paper journal is low — which is why computational correlation matters
the capture promise: one tap on a label or your voice — “coffee with milk and toast” becomes a structured entry, no forms
the pattern engine thinks on your phone, not in the cloud — zero server AI on the free plan; your data lives in your own private account, and export-all and delete-all are buttons
It feels like paper. It thinks in statistics.
Labels that learn from you (anything you log 3 times becomes permanent), an “all good” stamp for good days — no streaks, no guilt — and your history as a ledger with four calm ink charts.

A night mode of dimmed linen and light olive — warm, never surgical. And when you want more memory, a single membership adds reasoning over your long history. The same bright line: observe, correlate, prepare. Never treat.
Talk with your history
Months of entries, natural-language questions, longitudinal memory.
Weekly readings
Calm narratives with multi-factor patterns beyond the on-device engine.
A summary for your visit
Generated from your own journal — you decide what to bring.
Built first for one person.
This app exists because someone I love lives with a gluten allergy and colitis, and jotting everything into scattered notes never gave her a north — and the apps made her feel indebted to a streak.
So the pact is simple: your data is yours, the evidence states its own strength, empty days don't accuse, and the app prepares the conversation with your doctor — it never replaces them.
