Keep the detail you choose
Record a quick check-in, a meal, a symptom, or a note without turning your day into a project.
A private record, kept on your terms
GutLog is a local-first journal for the small details that are easy to lose track of. Capture what matters, return when it helps, and decide for yourself what a pattern means.
A record can have gaps. The point is not a perfect streak; it is a clearer place to begin.
A record with a purpose
Record a quick check-in, a meal, a symptom, or a note without turning your day into a project.
Look back across your own entries and their coverage. GutLog describes what is there; it does not diagnose you.
Review a personal export or a doctor-visit pack before you decide what to share and with whom.
A journal, not a diagnosis
GutLog gives you a place to keep observations together: what you recorded, when you recorded it, and how complete that record is. It does not label a day good or bad, or tell you what to do medically.
