How it works

From worried to well, in three steps.

01 · Snap

Show it what's wrong.

Up to three photos of the same plant. Add how the soil feels and the light it gets, two things a photo can't show.

02 · Understand

See what's likely, and why.

Likely causes with a confidence score, what to check first and what to avoid. Never a spray-from-a-photo verdict.

03 · Recover

Watch it come back.

A seven-day journal with a checklist, photo check-ins and height notes, so you can see new growth arrive.

Something wrong with a leaf? Ask the Plant Doctor.

Pick what you're seeing and tell it about the soil and light. Fernly works through the likely causes and builds a seven-day plan, using the same care guidance as the app.

Ready when you are

Most plants don't give up after one mistake. They fade from small changes nobody noticed. Fernly helps you notice.

Built in testing with real plants, real balconies and real weather.

Seven-day recovery journal

A checklist for day one, photo check-ins, height notes, and a reminder to compare new growth with the affected leaves at the end of the week.

Day 1 checklistPhoto check-insHeight notes

Garden timelines

A nickname, a room, a photo timeline and its height whenever you measure. Two measurements show the change.

Care tuned to your weather

Add your city and Fernly adjusts for heat, cold nights, and rain that may never reach a sheltered pot.

Reminders that ask you to check

Soil checks, treatments and progress photos. A reminder to check, never an order to water.

A library with its sources

106 plant guides checked against university extension services, with pet toxicity cited to the ASPCA or marked unknown.

Private by default

No account. Your garden lives on your phone, and a photo leaves it only when you tap Analyse, after you agree.

Care

Not every Tuesday. When the soil says so.

Fernly sets each plant's soil-check rhythm from its pot, its light, the season and your local forecast. Try the same rules the app uses.

  • Small pots dry faster, large pots hold moisture longer.
  • Lower light slows water use. Heat over 30 °C speeds it up.
  • Forecast rain never marks a plant as watered.

    Library

    106 plants, properly sourced.

    Care guides checked against university extension services. Pet toxicity cited to the ASPCA where it's known, and marked unknown where it isn't.

    Privacy

    No account. Your garden stays yours.

    Fernly opens straight to your plants. Nothing you add is tied to an email address or sent anywhere to sync.

    • Saved on your phone, not on our servers.

      Your garden, notes and progress photos live on the device. There is no cloud account to create.

    • Photos leave only when you tap Analyse.

      And only after you agree. Fernly tells you where they go before anything is sent.

    • Export or delete everything from Settings.

      One tap exports your garden as a file. Another removes it from the phone.

    Your plants are ready when you are.

    Coming to iPhone and Android. Free to start, no account, and your garden never leaves your phone unless you ask.
