Leafsight vs Plantum for a sick plant
Plantum, by AIBY, identifies plants (its store page says over 40,000 natural objects), has a plant disease identifier that lists treatment options, and adds care schedules and tools such as a light meter and a water calculator. It had 120,000 US ratings at 4.6 stars on 4 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 Plantum come from its US App Store page on 4 November 2026 and may have changed since; Leafsight is not affiliated with it.
Who each one is for
Plantum is for naming plants and looking after a collection: watering, misting, feeding and rotating schedules, a Light Meter, a Pot Meter, a Water Calculator and a Weather Tracker, and a vacation mode that shares the care schedule with someone else. The disease identifier is one feature among these. Its store page lists it in 9 languages.
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 | Plantum | |
|---|---|---|
| The main question | What is wrong with this plant? | What plant is this? (a disease identifier is a second feature) |
| 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 | A journal to see how plants grow is listed; a photo compared with the last one is not |
| Care steps | Non-chemical first, product types rather than brands, never a dose | A list of treatment options and plant health advice |
| Reminders | Check-in reminders to look at the plant again, and a Home Screen widget; no watering or feeding schedules | Watering, misting, feeding and rotating schedules |
| Extra tools | No | Light Meter, Pot Meter, Water Calculator, Weather Tracker |
| Languages | 8, including Korean | 9, including Italian and Traditional Chinese |

When Plantum is the better choice
- You want to know what a plant is. Leafsight will not tell you.
- You want care schedules and reminders for many plants, or someone to water them while you are away.
- You want a light meter, a pot meter or a water calculator in the same app. (For light, the free window light check on this site works without an app.)
- You read Italian or Traditional Chinese, which Leafsight is not in.
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 read Korean, which Plantum is not in.
- 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.
