food, symptom + daily life tracker
fern helps you find patterns between what you eat, what you do, and how you feel.
private by design. currently in limited beta.
for people who keep asking:
what changed?
most trackers collect data.
fern helps you find evidence.
how it works
track what happened, keep it connected, and let repeated relationships come back into view.
log food, symptoms, flares, routines, support actions, and daily observations in seconds.
when something feels off, you don't have to rely on memory.
everything lives together on one timeline, so meals, symptoms, routines, and observations stay in context.
no scattered notes. no trying to reconstruct your week from memory.
over time, fern surfaces repeated relationships from your own history.
not diagnoses. not prescriptions. just evidence that may be worth paying attention to.
what fern helps you see
a symptom appears on tuesday. again on friday. again two weeks later. you notice it each time, but never close enough together to realize it might be connected. fern was built to help those observations stay connected.
one timeline
a meal lives in one place. a symptom lives in another. a journal entry lives somewhere else entirely. fern keeps everything on the same timeline so the surrounding context stays intact.
your timeline
contextwhat tends to happen together
most appear quietly through repetition. the same symptom after the same meal. the same energy dip at the same point in your cycle. the same routine before a better week. fern pays attention to what repeatedly appears together so those relationships become easier to recognize.
soft connections
reflectwhat keeps coming back
something you logged three weeks ago becomes relevant today. a detail you forgot about starts showing up again. a connection that was impossible to see in real time becomes clearer in hindsight. not because fern tells you what it means. because it gives your own history a chance to stay visible.
quiet reflections
returnsome patterns are loud. others only appear quietly over time.
your inner world stays yours
everything you write to fern stays attached to you. nothing is sold, traded, or used to train external models.
only what you choose to log is stored. nothing pulled silently from your phone.
fern is built on early-access support, not on selling attention or behavioral data.
your reflections are not part of any external model training set.
ask us to remove your data at any time and it is gone.
