About this app
A quiet field-book for the plants on your shelves. Fern the Botanist keeps each plant on its own card — a name, a photograph, a steady record of how it's doing. No daily streak nags, no urgency. Plants keep their own clock. What you get • A private field-book for every plant you keep — orchids, ferns, succulents, the unnamed cutting from a friend • Quiet care plans: water, fertilize, mist, repot, prune — scheduled around the plant's pace, not yours • Photograph each plant; Fern notices the leaf you photographed, calmly, step by step • A weekly + monthly care calendar so today's tasks stay in view • Per-plant journal: every watering, every new leaf, every small concern logged on the plant's timeline • Pet-safety badges on the plants in your collection — a small green leaf for safe, a paw for "keep away" How it feels Fern speaks quietly, the way a fellow plant-keeper would — never as an expert lecturing the user. Roots first, then leaves. Slow water, steady light. A shelf grows one plant at a time, and the room stays quiet while it does. Who it's for • People who keep more than three houseplants and want a calm, private record of how each one is doing • Mature plant-keepers who are tired of busy plant-tracker apps and just want a quiet notebook • Anyone who has lost a beloved plant and wants to do better by the next one Privacy Your field-book lives on your device. Photographs and notes are never uploaded, indexed, or shared. Plant identification uses a single anonymous request per photo — the image isn't stored on our side. Safety No accounts. No social layer. No comparison to other plant-keepers. Fern only ever speaks to you. Slow water, steady light. Fern is ready when you are.
