Start with the symptom.
Log the thing you’re trying to understand: nausea, acne, bloating, headaches, fatigue, or whatever keeps happening.
You don’t have to know the cause yet. You only need to record what happened.

food, symptom + daily life tracker
fern helps you find patterns between what you eat, what you do, and how you feel.
For everyone who keeps asking…
What changed?
Fern gives the pieces somewhere to meet.






A meal from Tuesday. A symptom on Thursday. A difficult week. A routine that genuinely helped.
Alone, they are fragments.
Together, they become a life you can begin to understand.
HOW FERN WORKS
Start with what happened. Log the symptom you’re trying to understand, then keep the context around it.
Log the thing you’re trying to understand: nausea, acne, bloating, headaches, fatigue, or whatever keeps happening.
You don’t have to know the cause yet. You only need to record what happened.
Fern lets the rest of the day stay connected to the symptom.
Food, what you tried, and a daily check-in can sit around the same moment, without turning into a checklist of everything.
Meals, symptoms, things you tried, and the rest of the day stay connected instead of disappearing into separate notes and memories.
Today
Fern helps you notice what keeps showing up together.
Not a diagnosis. Evidence from your own history that may be worth paying attention to.

01
Something catches your attention before it has a meaning.
A symptom. A meal. A change in energy. A moment that feels different.
You do not need an explanation yet.

02
Keep the observations that would otherwise disappear into memory.
meals, symptoms, routines, support actions, ordinary moments.

03
Return to what you've collected and see what keeps appearing.

04
Recognition changes how you see the experience.
What felt random begins to have context.
What felt impossible to explain becomes easier to describe.

05
To what happened.
To what helped.
To yourself, with more context than before.
Evidence without overreach.
