how it works
fern helps you see patterns across the inputs that shape how you feel. no spreadsheets, guesswork, or scattered notes needed.
log what matters to you
track the inputs that shape your day. symptoms, food, movement, mood, cycles, or anything else you want to observe.
customize what you track. nothing is forced.
everything lives on one timeline
instead of scattered apps and notes, every input sits on a continuous timeline.
this makes relationships visible instead of fragmented.
fern evaluates patterns
when certain inputs consistently precede specific outcomes, fern analyzes frequency, proximity, and repetition.
understand what's shaping you
you start to see what repeats. what supports you, what drains you, what actually makes a difference.
clarity replaces guessing.
with fern, the goal is not to log for the sake of logging. it's to unearth relationships between patterns in your life that you couldn't see before.
