The fern that tells you what it needs.
Photo growth timelines, a page for every plant, lineage tracking, NFC tags, and care reminders — your whole staghorn collection in one calm place.
Watch it unfurl .
Snap a photo each month and Fern builds a timeline of every shield and antler. Before-and-after views make the slow progress you'd never notice day to day suddenly obvious.
A page for every fern .
A dedicated profile, photo log, and care history for each plant. Your whole collection becomes one tidy journal instead of a thousand-photo camera roll you can't search.
Map every pup .
Trace propagations from mother plant to pup with a visual lineage chart — then write an NFC tag and tap your phone to open a plant's profile the instant you walk up to it.

Built specifically for staghorn growers — not a generic plant app.

“The long-image export in the Growth Timeline turns every Ridley from pup to trophy size into one beautiful vertical image. And my data stays on my device — total peace of mind.”
“I raise separated pups, so I wanted to organize parent and offspring. Fern records which mother produced which pup, the division date, and each generation's growth — a complete family tree.”
“It helped me dial in the perfect humidity and lighting for my staghorn. My fern has pushed out two massive new fronds since I started using it.”
