Leafsight vs PlantIn for a sick plant
PlantIn identifies plants and also offers a disease identifier, a pest identifier and a botanist to ask, in the app and in a browser on its website. It had 230,000 US ratings at 4.6 stars on 1 November 2026. Leafsight does one thing: it assesses a plant that looks wrong. If you are choosing between them for a sick plant, this is the honest comparison.
This page is written by the maker of Leafsight. The facts about the other app come from its US App Store page and its website on 1 November 2026 and may have changed since; Leafsight is not affiliated with it.
Who each one is for
PlantIn is for naming a plant and keeping a collection, with problem tools beside that: its website offers a plant identifier, a disease identifier and a pest identifier that work in the browser, a blog, and a botanist to ask, in 7 languages. It runs on iPhone, iPad, Android and a browser identifier on its website.
Leafsight is for the moment a plant looks wrong. You photograph the leaf and get an assessment of the likely problem, how serious it looks, how sure the model is, and what to try first, with non-chemical steps first. It does not identify species. It runs on iPhone and iPad only, in 8 languages.
What each does with a photo of a sick leaf
| Leafsight | PlantIn | |
|---|---|---|
| The main question | What is wrong with this plant? | What plant is this? (a disease identifier is a second tool) |
| Names the species | No | Yes |
| Shows how sure the model is | On every result | Not listed on its store page |
| Says what it cannot see | On every full result (roots, soil, the room) | Not listed on its store page |
| A second photo compared with the first | Yes: it says whether the plant looks better in the new photo | Not listed on its store page |
| A person to ask | No: it sends you to a garden centre or plant clinic | Yes, "Ask the botanist"; the developer's reply on its store page says the subscription does not include it |
| Works in a browser | No (the guides on this site do) | Yes, on its website |
| Platforms | iPhone and iPad | iPhone, iPad, Android and a browser identifier on its website |
| Languages | 8 | 7 on its website |

When PlantIn is the better choice
- You want to know what a plant is. Leafsight will not tell you.
- You are on Android, or you want to try a photo in a browser before installing anything.
- You want a person to ask, and don't mind that it is a separate purchase from the subscription.
- You keep a large collection and want identification and care in one place.
When Leafsight is
- One plant looks sick and you want to know how sure the answer is before you act on it.
- You want to take a second photo in two weeks and be told whether it looks better.
- You want the price in front of you before any trial starts, and the first result's care steps without paying.
Leafsight is new (its first version was released in September 2026) and has no ratings shown on its US App Store page yet. Every result shows how sure the model is, the full result says what one photo cannot show, and a photo assessment can be wrong: for a valuable plant, or anything you might eat, ask a garden centre or a plant clinic.
Try it on the plant in front of you
Leafsight is free to download. Take a photo of the leaf and read the assessment; the first result's care steps are free. The plant problem guides on this site explain the common problems in plain words, in 8 languages.
