Not a plant app.
A logbook.

General plant apps keep a windowsill alive. Fern is built for mounted staghorn ferns — and for the people who watch them grow for years.

5.0 on the App Store · 1M+ downloads

Mounted, not potted

Built around boards

Remounting, algae on the mount, NFC on the board, a wall that hangs the way yours does.

A logbook, not a nag

Every frond, dated

Most plant apps stop at reminders. Fern keeps the photo history that shows a slow plant growing.

Collector-grade

Lineage to spores

Track pups back to the mother plant and sowings through nine stages to a sporing adult.
