Plantix is a genuinely excellent, free crop-disease app — built for farmers, covering around 30 major crops and 780+ problems, with treatment suggestions. If you grow field crops, it may be all you need (its free tier does show ads).
Flora Incognita is one of the best free, ad-free plant identificationapps there is — developed by scientists, excellent on European flora. If your question is “what is this plant?”, reach for it. It doesn't, however, diagnose diseases or cover houseplant problems.
That's the honest gap Dr. Phytofills: telling you what's wrongwith a home or ornamental plant, how sure it is, and exactly how to treat it within EU rules. Here's the whole picture side by side.

Questions people ask
What is the best free plant disease identification app?
It depends on what you grow. For field crops, Plantix is excellent and free (with ads) — it's built for farmers and covers around 30 major crops. For simply identifying which plant you're looking at, Flora Incognita is outstanding: free, ad-free and research-backed, though it doesn't diagnose diseases. For a home or ornamental garden where you need to know what's wrong and how to treat it, Dr. Phyto gives you a free first diagnosis that names the pathogen, states a confidence level, and gives EU-approved treatment steps.
What app tells you what's actually wrong with your plant?
That's a diagnosis tool, not an identification one. Flora Incognita tells you what the plant is; it doesn't diagnose problems. Plantix diagnoses diseases on supported crops. Dr. Phyto is built specifically to tell you what's wrong with a plant — from a photo it names the likely disease or pest, says how confident it is, weighs up similar-looking conditions, and gives a treatment plan with products and dosage that are approved in the EU.
Does Flora Incognita detect plant diseases?
No — Flora Incognita is a plant identification app. It's one of the best free, ad-free tools for working out which species a plant is, developed by scientists and strong on European flora. But it doesn't diagnose diseases or pests, and doesn't cover houseplant problems. For that you need a diagnosis tool such as Plantix (crops) or Dr. Phyto (home and ornamental gardens).
Is Plantix good for houseplants and ornamental gardens?
Plantix is superb for what it's designed for — field crops and agriculture — and it's free. It's less focused on ornamental plants, houseplants and mixed garden borders, and its free tier shows ads. If your problem is a sick olive tree, a diseased rose or a struggling houseplant rather than a cereal or vegetable field, a consumer-and-ornamental tool like Dr. Phyto will usually fit better.
Can you trust an AI plant diagnosis?
Trust comes from honesty about uncertainty. A tool that always sounds 100% sure is the one to be wary of. Dr. Phyto states a confidence level with every diagnosis, rules out look-alike conditions before deciding, and is transparent when a case is unclear — and its treatment advice is bounded by what's actually approved in the EU. The best practice with any AI tool is to treat a confident, well-explained answer as a strong starting point, not an infallible verdict.
Which plant app is best for the EU specifically?
Dr. Phyto is built around European reality: it works in five EU languages, its treatment advice uses only EU-approved active ingredients with correct dosage and bee-safe timing, and it flags notifiable quarantine pests such as Xylella and points you to the right authority. Plantix and Flora Incognita are both strong tools but aren't built around EU plant-health regulation in that way.
