The best plant identification apps, by situation

How we compared

We make Plant Identifier. We compared the other apps on what each one documents publicly. We did not use them or run lab tests; the test above is yours to run.

• Criteria: what the app is for (wild plants, houseplant care, or everything), what it costs, whether it identifies without a connection, whether it needs an account, whether it runs on Android or the web, and whether a result shows other candidates.
• Where the facts come from: each app's US App Store listing (price row, In-App Purchases list, description), its own website, help pages and documentation, and for accuracy, published studies only. Accuracy figures an app gives about itself are not repeated here.
• When: every price, rating count and feature was checked on 2026-10-21. Ratings are quoted as "N ratings, average X, US App Store". Prices change; the listing is always the final word.
• What we left out: anything an app's own pages don't say. "Not documented" here never means "no".
• About our app: we publish no accuracy figure for Plant Identifier, because none has been measured independently.

Wild plants in Europe: Pl@ntNet and Flora Incognita

Both are free, list no in-app purchases on their US App Store pages, and are run by public research institutes. If most of what you photograph grows wild, start with one of these.

Pl@ntNet: several photos, ranked candidates, the web and Android

Pl@ntNet, listed as PlantNet, is a citizen-science project governed by a consortium of five research organisations (CIRAD, Inria, INRAE, CNRS and IRD). Its documentation says you take one or more photos, say which organ each one shows (leaf, flower, fruit), and get "a list of possible identifications, ranked by order of certainty". You can choose a regional flora, use it in a web browser or on Android, download an offline model to the mobile app, and since March 2026 identify diseases and pests too. Its listing says wild plants come first and cultivated garden plants are "not its primary purpose". 7,049 ratings, average 4.59, US App Store, checked 2026-10-21.

Flora Incognita: guided photos, free of charge and advertising

Flora Incognita is developed by scientists at TU Ilmenau and the Max Planck Institute for Biogeochemistry. Its FAQ says the app "is completely free of charge and advertising", that you "do not need a profile to identify plants", and that without signal it saves observations of three pictures per plant (usually flower, leaf and whole plant) to identify once you are back online. Its website says it identifies more than 30,000 plant species. Most of its ratings come from Germany: 27,004 there at 4.8, against 595 in the US at 4.79 (checked 2026-10-21). For the two side by side, see Flora Incognita vs Pl@ntNet.

Wild plants in North America and nature logging: Seek and iNaturalist

Both come from iNaturalist, a non-profit, and both cover animals and fungi as well as plants. The iNaturalist help centre explains the split.

Seek by iNaturalist is for families and for places without signal: "No account required, designed to be safe for children", and "the app does not require an internet connection to work". It identifies live through the camera and adds badges and challenges. The trade-off, in the same article: Seek's model "is generally going to be older than the current online model". 30,912 ratings, average 4.75, US App Store, checked 2026-10-21.

iNaturalist is for logging what you find. Its AI suggests a name, then a global community of naturalists can confirm or correct your observation, which can become data for science. That human check is something no purely automated app offers. The redesigned app is listed "Only for iPhone" (706 ratings, average 4.08, US App Store, checked 2026-10-21); iNaturalist also runs on the web and has a separate Android app.

Houseplant care with reminders: PictureThis and Planta

If what you want is a schedule that tells you when to water, these two document it. Both are free to download with paid subscriptions.

PictureThis, listed as PictureThis - Plant Identifier, carries an Editors' Choice badge and is the most-rated plant identifier we measured on the US App Store: 1,120,486 ratings, average 4.8 (checked 2026-10-21). Its US listing describes diagnosis with "a step-by-step treatment plan", care tips and reminders, a water tracker, toxic-plant warnings and weed identification, and it also runs on Android and the web. It sells PictureThis Pro, with a free trial whose length the listing doesn't state, and a Family Plan; in-app purchase rows ran from $3.99 to $49.99 on 2026-10-21. If it is on your shortlist, see PictureThis vs Pl@ntNet, or the PictureThis alternatives page if you are thinking of leaving it.

Planta, listed as Planta: Plant & Garden Care, is a care app first, with an Editors' Choice badge and 114,278 ratings, average 4.75, US App Store (checked 2026-10-21). Its US listing describes care schedules for watering, fertilizing, repotting, pruning and misting that "adapt to your home environment, local weather, and plant type", Dr. Planta for symptoms, a light meter and identification. It sells Premium Plant Care subscriptions of 1, 3 and 12 months: in-app purchase rows from $7.99 to $45.99, plus a 12-month plan at $47.99 on the Subscriptions shelf (2026-10-21), and needs iOS 18 or later.

Nothing to install: Google Lens and Apple Visual Look Up

You may not need a plant app at all. On an iPhone with iOS 15 or later, open a photo in the Photos app and tap the Info button; when a leaf icon appears on or below the photo, tap it. Apple's support page says results come "from Siri Knowledge and the web", and that the feature also works in Notes, Mail, Messages and Safari. If the Info button has no star, Visual Look Up has nothing for that photo.

Google Lens does the same job inside the free Google app on iPhone, on Android and in Chrome on a computer; Google's own example is finding out "what plant is in your friend's apartment". Both are generalists that also recognize animals, landmarks and text, so they give a quick name rather than a plant profile. Our guide to identifying plants on iPhone walks through both.

Where Plant Identifier fits

Plant Identifier, listed as AI Plant Identifier Flower App, is for the houseplant on your windowsill and the flower in your garden when you don't know where to start. One photo, from the camera or your library, returns the common and scientific names, origin, growing conditions and key traits. From the same home screen, Diagnose checks a spotted or yellowing plant and gives a severity badge the AI writes, a likely cause and treatment steps; Toxicology gives AI-written notes on toxic parts and symptoms for people, dogs and cats, which a vet or poison centre should confirm. Under each result you can ask follow-up questions, and the Plant Expert tab has an AI assistant called Flora for longer ones. The app's screens are in six languages: English, Italian, German, French, Spanish and Portuguese (Brazil).

It is free to download, and the current version (1.0.6) shows no paywall. Ratings: 303 on the US App Store, average 4.81, and 4,333 across 30 storefronts, average 4.66, most of them from Italy and Germany (checked 2026-10-21).

Its gaps, plainly: it shows no confidence score and no list of alternative species, it takes one photo per identification, it needs an internet connection every time because the photo goes to a cloud AI model, it sends no watering reminders, and it is iPhone only (it runs on iPad in iPhone layout; there is no Android version).

Where we're not the pick

• You want to see how sure the app is. Pl@ntNet shows candidates ranked by certainty; Plant Identifier gives one name.
• You are often without signal. Seek needs no connection, and Pl@ntNet identifies without one once its offline model is downloaded. Plant Identifier can't identify offline.
• You want people, not only a model, to check. iNaturalist's community confirms observations.
• You want reminders to water and feed. PictureThis and Planta document them; Plant Identifier has none.
• You or your family use Android or a computer. Pl@ntNet, iNaturalist, PictureThis and Google Lens all do; Plant Identifier is iPhone only.
• You record wild plants for science or a survey. Pl@ntNet, Flora Incognita and iNaturalist are built for that.
