Google Lens vs plant identification apps

How we compared

We make Plant Identifier, so it is in the table above and in its own section below, with its limits listed. For Google Lens we read Google's Lens page, its "Search with an image" help article for iPhone and Android, its Search Services History help articles, and the Google app's US App Store listing (price, in-app purchases, compatibility). For Pl@ntNet, iNaturalist and Seek we read their App Store listings, Pl@ntNet's documentation and iNaturalist's help center. All on 2026-10-21. We did not run a lab test of any app. For accuracy we cite a peer-reviewed study, not any app's claim about itself. Where a page says nothing, we write "not documented", which is not the same as "no". The Google app's ratings belong to the whole app, not to Lens, so we leave them out.

What Google Lens does well for plants

It costs nothing and is close at hand. The Google app is free to download; its In-App Purchases section on the US listing lists Google storage and AI plans, from "30 GB: $0.89" to "Google AI Plus (2 TB): $99.99" (2026-10-21), none of them needed for Lens. It requires iOS 16.0 or later on iPhone and iPadOS 16.0 on iPad.

It searches everything, not only plants. One camera covers plants, animals, text and products, so you don't need a separate app for a one-off question. For a plant that is a popular cultivar or a houseplant sold everywhere, the web is full of matching photos, and Lens's similar-image results play to that.

You can ask about the photo. Google's Lens page says to "hold the shutter button and ask whatever's on your mind", so a question like "is this a perennial?" can travel with the image. Treat the answer as a lead to check, as you would any search result.

It has been tested. Google Lens is one of the few general tools in a peer-reviewed comparison. In Hamlyn Jones's 2020 study in AoB PLANTS, nine apps each identified 38 images of 24 British wild species five times. Lens named the species correctly on its first answer 45% of the time and reached the right genus or better 56% of the time, third of nine for species behind Plant.id (57%) and Flora Incognita (46%), and ahead of PlantNet (39%) and Seek (35%). That is one test of wild plants in one country, with apps as they were in 2020. Our page on how accurate plant identification apps are sets it beside the other studies.

Where dedicated plant apps differ

Curated plant databases instead of the web. Lens matches your photo against the web at large. Plant apps match against plant data: Pl@ntNet's listing says it can "recognize about 20,000 species" and organises them in floras by region or theme, and iNaturalist's model is trained on photos from observations on iNaturalist, where its community adds identifications. A plant-only set keeps the answer to plant species, and on Pl@ntNet it can be narrowed to the flora of your region.

Several photos, tagged by plant part. Pl@ntNet's listing says flowers, fruits and leaves "are the most characteristic organs of a species and it is them that should be photographed first", and its app asks you to say which organ each photo shows. Lens takes one image at a time; you can select part of it, but you can't tell it that photo two is the fruit of the plant in photo one.

Candidates rather than one answer. Pl@ntNet returns a ranked list of possible species, so you can compare the runner-up against the plant. Lens returns search results and an AI overview; it is up to you to judge which match is right.

Care, diagnosis and safety notes. Dedicated apps add plant-specific follow-ups: Pl@ntNet identifies diseases and pests since March 2026 (without treatment advice, per its docs), and care apps such as the ones in our best plant identification apps roundup add schedules and diagnosis. None of this replaces a vet or poison control if a pet or child has eaten a plant: in the US, call the ASPCA Animal Poison Control Center at (888) 426-4435 or Poison Control at 1-800-222-1222.

Collections and records. iNaturalist's listing promises to "keep a record of species you see", Pl@ntNet lets you share observations with its community once you have an account, and Seek awards badges as your list grows. Lens is a search, and the pages we read do not describe a plant list.

People in the loop. On Pl@ntNet, shared observations are "reviewed by the community" (listing); on iNaturalist other members confirm IDs. Lens has no reviewer. For which of the two free research apps suits you, see Pl@ntNet vs iNaturalist.

Privacy, as each publisher documents it

From each publisher's own help pages and documentation, read on 2026-10-21.

• Google Lens: Google's saved-media help article says that when you are signed in, Google can save "your images, files, audio and video" from Search services, "Google Lens images" included, to your Search Services History. Saved media "may be used to develop and improve Google's AI models"; media used for training "is disconnected from your Google Account and retained for up to 4 years". You can uncheck "Save media", but media already saved stays until you delete it. Its history article adds that saved activity can include "info about your location from your device's general area and IP address". Google says these settings are still rolling out; where they are not, Web & App Activity controls them.
• Pl@ntNet: its data page says it "does not share its users' personal data with third parties". Shared observations make "images, identifications, and plant locations" public if you made them public; for rare or endangered species you can keep the location confidential.
• Seek: iNaturalist's help center says "the data you record does not leave your device", and that no personally identifiable information is collected from users who do not log in.
• Plant Identifier (ours): per our privacy policy, the photo, your approximate location (only if you allow it, or if the library photo you choose carries one), the text of your chat messages and a random install and device identifier go to our server, which passes requests to Google (Gemini) and, when Google's service fails, to OpenAI. There is no account, and our server does not store your photos or messages.

Where Plant Identifier fits (ours)

This section is about our own app, so weigh it accordingly. Plant Identifier, listed on the US App Store as AI Plant Identifier Flower App, is an iPhone app for houseplants, garden plants and flowers. One photo gives the common and scientific name, origin, growing conditions and characteristics, then three suggested follow-up questions and a chat under the result. Diagnose gives a likely cause with a severity badge the AI writes, affected areas, treatment steps and prevention; Toxicology writes AI notes for people, dogs and cats that need a professional's check. Each identification lands in Plant History and, for 150 common species, fills in the Collection catalog; located finds appear on the Plant Map. It is free to download and the current version shows no paywall. On 2026-10-21 it had 4,333 ratings averaging 4.66 across 30 App Store storefronts.

Where we're not the pick

• A one-off name with nothing to install: Lens, or Visual Look Up in the iPhone's Photos app (see identifying plants on iPhone).
• Android, a desktop or a web page: Lens covers all three. Plant Identifier is iPhone-only and runs on iPad in iPhone layout.
• Several photos, or a list of candidates: Pl@ntNet. Plant Identifier takes one photo and shows one name, with no alternatives.
• No signal: Seek, or Pl@ntNet after its download. Plant Identifier needs a connection for every identification.
• Independent evidence: Lens, Pl@ntNet and Seek appear in published tests; Plant Identifier does not.
