Step one

Take one photo of the sick part

A single leaf filling the frame works best. No forms to fill in, no species encyclopedia to search, no account to create. You photograph the thing that worries you, and that is the whole job.

Step two

Get a ranked diagnosis, with the evidence

Plant problems look alike, so a single confident verdict is usually a guess. PlantRx gives you the likely causes in order, and under each one, exactly what in your photo led there: the white powdery patches, the yellowing on the older leaves. You can check its reasoning against your own eyes.

Step three

Then do exactly what it says

Numbered steps in the order you should do them, then what to expect and when. No new white patches within one to two weeks means it is working. Afterwards it asks how it went, and your answer makes the next diagnosis better.

Built to be honest on the days it is not sure

Not sure? Not charged.

When the photo cannot support a confident diagnosis, PlantRx says so and asks for a better photo instead of billing you for a guess. The unsure answer is free.

Your history stays put

Every diagnosis is saved with its photo, so you can see how a plant looked three weeks ago and whether the treatment worked. You can delete any photo. We never delete it for you.

No account, ever

No sign-up, no email, no password. Your plants are not a mailing list. The app works the moment it finishes installing.

One price, not a subscription

Most plant apps charge about $40 a year. Every year.

We would rather sell you the thing once. Start with a free diagnosis, in full, not blurred. Then, if PlantRx earns it:

5 Diagnoses$4.99

Five full diagnoses that never expire. They wait, for as long as your plants stay healthy.

  • No subscription
  • Never expires
  • Nothing to cancel
PlantRx pricing screen: Unlimited Forever for $34.99 or 5 Diagnoses for $4.99, both one-time payments

Free plant problem guides

Written the same way the app works: the competing causes ranked, what else you would see if it were each one, and the single check that settles it.

What PlantRx will never do

We never advise on whether a plant is safe to eat or touch, and we never tell you a plant is safe for a child or a pet. If a child or animal may have eaten part of a plant, contact Poison Control (US 1-800-222-1222) or a vet immediately.

The plant is worth saving.

One photo, a real diagnosis, and a plan.
The first one is free.
