One of the most accurate and polished plant identification apps, held back by an aggressive subscription push.

What could be better
- −Subscription offer appears immediately and is easy to trigger by mistake

Best for: Houseplant owners and gardeners who want identification plus care help
Visit Glority Global Group Ltd. →This PictureThis review covers one of the most downloaded plant identification apps, an Apple Editors' Choice pick with a 4.8-star rating from more than a million reviews on the US App Store. People searching for it usually want to know how accurate it is, whether PictureThis is free, and whether the Pro subscription is worth paying for.
Our assessment is based on the developer's own descriptions and store listings, independent reviews from gardening and technology sites, and patterns in user feedback.
How PictureThis works
You point your phone at a plant, take a photo of a leaf, flower or the whole plant, and PictureThis returns a likely match within seconds, with alternative suggestions if it is unsure. Each result opens a detailed profile covering common and scientific names, characteristics, growing conditions, care tips and whether the plant is toxic to people or pets.
Identified plants can be saved to a personal collection, which becomes the hub for reminders and care notes.
Identification accuracy
Glority says PictureThis identifies plants with over 98 percent accuracy, a figure that comes from the developer rather than independent testing. Independent reviewers and user reports generally place it among the more accurate consumer plant apps, particularly for common houseplants, garden flowers and trees.
Like every photo-based tool, it struggles with poor images, young seedlings, non-flowering grasses and rare or regional species. Taking a sharp photo of a flower or leaf in good light and photographing several parts of the plant improves results. For anything you plan to eat, never rely on an app alone.
A practical tip is to check the alternative matches the app offers rather than accepting the first suggestion. Comparing the reference photos with your plant, looking closely at leaf shape, flower structure and growth habit, catches most errors. When results conflict, a second opinion from a free community app or a local garden centre is sensible.
Plant care, diagnosis and extra tools
PictureThis goes beyond identification. The diagnosis feature analyses photos of sick plants and suggests likely causes, such as overwatering, pests or fungal disease, along with treatment steps. Care reminders prompt you to water and fertilise, and a light meter tool estimates whether a spot gets enough light.
Other features include weed identification with removal tips, a wishlist for plants you want to buy and access to botanical experts for questions.
For outdoor gardeners, weed identification is surprisingly handy. It helps you decide whether a seedling is a welcome self-sown flower or something to pull, and the app offers guidance on how to deal with unwanted plants. Pet owners will appreciate the toxicity warnings, which flag common houseplants that can harm cats and dogs.

Free vs PictureThis Pro
PictureThis is free to download, but free use is limited, and the app strongly promotes PictureThis Pro from the first launch, typically with a free trial that converts to a paid annual subscription. The largest volume of complaints in user reviews concerns unexpected charges after the trial, so set a reminder to cancel if you only want to test it.
Pro unlocks unlimited identifications, full diagnosis and care features, and removes restrictions. A family plan is also offered.
Design and ease of use
The app is polished and easy to navigate. A large camera button sits at the centre, results appear with clear photos for comparison, and plant profiles are laid out in readable sections. Tips on taking better identification photos appear in the camera view, which helps beginners get more accurate matches.
The home screen mixes your plant collection with articles, seasonal gardening tips and prompts to upgrade. Some users find the frequent upgrade prompts distracting, but once you know where things are, everyday use is quick. Support for around 28 languages makes it usable for gardeners in most European countries, including German.
Privacy
Like most identification apps, PictureThis uploads your photos for analysis and may use location data to refine suggestions. Check the permissions you grant, and switch off precise location if you do not want garden photos tied to your address.
Who should use PictureThis?
PictureThis suits houseplant collectors and home gardeners who will use care reminders and diagnosis regularly, where the Pro subscription earns its keep. If you only want to name the occasional wildflower on a walk, a free tool such as Pl@ntNet, iNaturalist or Google Lens will do the job without a subscription.
Teachers and parents may also find it a fun way to get children interested in nature, as long as someone keeps an eye on in-app purchase settings. Serious botanists and ecologists will want citizen-science tools that record observations with community verification, which is where iNaturalist shines.

Frequently asked questions
Is PictureThis free?
+
The app is free to download, but free use is limited. Unlimited identifications, full diagnosis and care features require PictureThis Pro, which usually starts with a free trial.
How accurate is PictureThis?
+
The developer claims over 98 percent accuracy. Independent reviewers generally rate it among the more accurate plant apps, but results depend on photo quality and the species.
Is PictureThis worth paying for?
+
It is worth it if you care for many houseplants or a garden and will use diagnosis and reminders. For occasional identification, free apps like Pl@ntNet or iNaturalist are enough.
How do I cancel my PictureThis subscription?
+
Cancel through your App Store or Google Play subscription settings, not by deleting the app. Do it before the trial ends to avoid being charged for the year.
Can PictureThis diagnose plant diseases?
+
Yes. Its diagnosis tool analyses photos of affected plants and suggests likely problems and treatments. Treat results as guidance, especially for serious infestations.
Is PictureThis safe for identifying edible plants or mushrooms?
+
No app should be trusted alone for foraging. Misidentification can be dangerous, so confirm with an expert or a reliable field guide before eating any wild plant.
PictureThis is one of the most accurate and feature-rich plant identification apps available, and its care tools genuinely help houseplant owners. The catch is the aggressive subscription funnel. Use the free trial carefully, decide whether you will use diagnosis and reminders often, and if not, stick with a free alternative.
