In short
Our pick
To identify and then actually grow the plant: Plantalya. To identify only, especially in the wild: Pl@ntNet. Nothing stops you from using both — plenty of people we hear from do.
We're not going to give you an "accuracy percentage" for any of these apps. Those numbers shift with the photo, the light, and the plant, nobody measures them the same way, and several apps publish figures on their own store listings that we simply can't verify independently — so we're leaving them out entirely, including for Plantalya. Instead, we looked at five things you can check yourself: what the app does after naming the plant, whether it diagnoses a problem, whether it shows its sources, what languages it's actually written in, and what it costs.

How we compare
We compare what can be checked: the features each app publicly documents, what its free tier actually includes, and the price shown on its own store listing. We do not measure identification accuracy, because we have no way to test it fairly, and we never publish a percentage we cannot reproduce.
Plantalya is our own app, so this page is not neutral and we will not pretend it is. What we can promise: no money changes hands with the apps compared here, there are no affiliate links, and nothing on this page was paid for.
If you only want a name
Pick Pl@ntNet. It's free, it's run by a French public research institute, and your photos feed actual biodiversity research. For wild flora specifically, it's the reference point — we're not aware of a free alternative that matches its scientific backing.
If you want to keep the plant alive
That's where identification stops being the point. What matters is the guide that comes after. We built Plantalya around that idea: every plant has its own page, written for that species, covering light, watering, soil, temperature, toxicity, and the source behind each figure. You can read these guides right here, without installing anything — our Monstera deliciosa guide is a representative example.
If a specific plant is already struggling, our plant diagnosis tool walks through likely causes rather than just naming the species again. And if pets are part of the household, our pet-safe plants tool is built for that one question specifically.
Common mistakes with identification apps
- Confusing two close cultivars: always double-check with a second photo — leaf and stem, not just the flower.
- Photographing from too far away: frame a single leaf clearly, straight on, in good light.
- Trusting the first result without checking the alternatives the app usually offers below it.
- Assuming a high confidence score means certainty — none of these apps, including ours, should be treated as infallible on a plant that matters (say, before eating something wild).
What we haven't verified
We could not confirm official, current subscription prices for PictureThis, Planta, or PlantIn — App Store listings showed multiple, sometimes conflicting figures for the same plan length, which looks like promotional pricing captured mid-change rather than a single stable rate. We also couldn't confirm whether PictureThis's "expert consultation" chat is staffed by humans, AI, or both — sources disagree. We left both kinds of claims out rather than guess.
Frequently asked questions
Which app is most accurate at identification?
We're not publishing a ranking on this, because no source we found measures accuracy the same way, and the percentages some apps advertise aren't independently verifiable. What we can say: PictureThis and Pl@ntNet both claim very large recognition databases (400,000+ and ~20,000 species respectively, per their own listings).
Is there a free option that's actually free, no catch?
Yes — Pl@ntNet. Its App Store listing shows no in-app purchases at all, and independent sources consistently describe it as non-profit and publicly funded.
Do I need to create an account to identify a plant?
It depends on the app. Plantalya's web encyclopedia (503 plants) is readable without an account; several competitors' web libraries push toward app installation or account creation for full access, based on what we could check on their sites.
