Best mushroom identification app: an honest comparison (2026)

The short answer

No mushroom identification app is good enough to decide, on its own, whether a mushroom is safe to eat. That includes ours. The only peer-reviewed comparison we found (Hodgson et al., Clinical Toxicology, 2023) tested three popular apps on 78 specimens sent to a poison center. The best, Picture Mushroom, identified 49% of specimens correctly and 44% of the poisonous ones. The authors concluded the apps "are not reliable enough to exclude exposure to potentially poisonous mushrooms when used alone."

So the useful question is not "which app is right most often" (nobody has published that for the current apps) but "which app is honest about what it does not know". Use any app as one input among several: a free community app such as iNaturalist, a field guide for your region, and a local mushroom club. The guide are mushroom identification apps accurate? explains why photos fail.

How we compared

We did not run our own accuracy test: a fair one needs expert-confirmed specimens, and a test run by one vendor is worth little to you. Instead we compared the apps on things you can check yourself in five minutes:

1. Does it lead with edibility? Is the verdict the first thing on the result?
2. Does it show confidence, and other candidates when unsure?
3. Does it name look-alikes, with how to tell them apart?
4. Does it state its limits? A photo cannot show a spore print, a smell or a buried stem base.
5. Price and paywall clarity, before you start.
6. Platforms and maintenance. iPhone, Android, and when it was last updated.

Prices are US store prices on 2026-10-31; they change and vary by country. We do not print competitor star ratings or download counts: they are easy to game and say nothing about safety.

The options

Mycoscout (our app)

Mycoscout photographs a mushroom from up to four guided angles (cap, gills, stem including the base, habitat) and shows the edibility verdict in a band at the top of the result, then the most likely species, a confidence badge (LIKELY, PROBABLE or UNCERTAIN), a checklist of features to confirm yourself, and the dangerous look-alikes with "tell apart" and "risk" lines. When unsure it lists other possibilities. Edible verdicts always read "verify before eating".

• Price: 3 free identifications, then Mycoscout Pro at $29.99 per year with a 7-day free trial, or $3.99 per week (App Store, 2026-10-31; Google Play, $3.99–$29.99 per item, updated 2026-09-27).
• Platforms: iPhone (iOS 15 or later) and Android. Version 1.0.2, released 2026-10-21. First released 2026-09-24, so it is the newest app here and has no published accuracy test.
• Limits: needs an internet connection; no maps, offline mode, spore prints or expert consultation. A field companion, not a mycologist.

Picture Mushroom (Next Vision Limited)

The best-known mushroom app, from the family behind PictureThis. The App Store listing promises "Unlimited IDs, toxicity ID", habitat information, foraging-site tracking, a distribution map and "free consulting with experts" for Premium members; the website calls it an "AI mushroom expert in your pocket" (App Store and picturemushroom.com, 2026-10-31).

• Price: free to download. The US App Store lists "Picture Mushroom Premium" in-app purchases from $2.99 to $39.99 plus "No Ads" at $0.99; the description says "Yearly Premium … 1 year (7 days trial)" but not which listing is the yearly plan. Google Play lists items at $0.99–$32.99 (Google Play, 2026-10-31).
• Platforms: iPhone (iOS 15 or later) and Android. iOS version 2.14.0 released 2025-10-29; Android updated 2026-09-18.
• Published test: 49% overall, 44% on poisonous species, the best of the three apps tested with 2020–2021 versions (Hodgson et al. 2023).

Spore AI (Massimiliano Merlo)

The closest app to a safety-first positioning. Its store page lists "AI Mushroom Identification, Toxicity Information, Exposure Assessment, Symptom Progression Timelines, Habitat and Seasonality, Detailed Reports" (App Store, 2026-10-31). Its website states "14,000+" species and "94%" identification accuracy; we found no published test behind those figures and the store listing does not repeat them (sporeai.app, 2026-10-31).

• Price: $4.99 per month or $29.99 per year, 3-day free trial. The app "requires an auto-renewable subscription to unlock mushroom identification", so there are no free identifications.
• Platforms: iPhone (iOS 15 or later); the website links to the App Store only.
• A caution: the store page itself says the app is not medical, veterinary or poison-control advice. If someone has eaten a mushroom, call poison control, not an app.

ShroomID (ZH Creations LLC)

Take a picture and the app suggests a match; you can filter by color, shape and habitat and ask other members for help. Species entries show an edible or toxic status (App Store and shroom.id, 2026-10-31).

• Price: free to download; the US App Store lists monthly purchases at $4.99 and $9.99, yearly at $27.99 and $29.99, "ShroomID Pro" $4.99 and "ShroomID Premium" $27.99, without saying which is current. No free trial is mentioned.
• Platforms: iPhone (iOS 12 or later) and Android. The iOS app was last updated on 2023-11-17 (version 2.26.8). Three years without an update is a reason for caution with a safety app.

Shroomify - Mushroom ID USA (Simon Grogan)

A paid app with no subscription: $5.99 one-time, no in-app purchases. "Identification, the field guide and your logbook work offline once installed", with "400+ species with 1,000+ photographs and regional datasets" (App Store, 2026-10-31). iPhone (iOS 15 or later), version 2.1.33 released 2026-10-10; we did not verify an Android version.

Mushroom Identificator (AnnapurnApp Technologies)

Also called "Champignouf". It "recognises more than 2000 types of mushrooms" (App Store, 2026-10-31). Free to download, with in-app purchases at $4.99, $7.99 and $24.99; the description also mentions a "premium subscription option $4.99 (USD) for a year", which does not match the list. iPhone only (iOS 15.5 or later), version 1.35 released 2026-09-05. In the 2023 study it scored 35% overall and 30% on poisonous species.

Free apps: iNaturalist and Seek

iNaturalist is "free, nonprofit, community-powered". You upload a photo, "the app suggests an identification instantly, and a global community of naturalists confirms or refines it". An observation becomes "Research Grade" when "more than 2/3 of identifiers agree on a taxon at species-level" (iNaturalist help, 2026-10-31). That human step is the point, and it takes hours or days. No edibility verdict, and community agreement is not a clearance to eat. iOS version 1.2.1 released 2026-10-21; Android updated 2026-10-15. In the 2023 study its AI suggestion scored 35% overall, 40% on poisonous species and 27% on death caps.

Seek by iNaturalist is the same organization's camera app: free, "does not require registration and does not collect any user data by default". Its 2020 user guide says the identification "does not leave your device or require an internet connection" and that the camera "does not know everything, so it may be wrong" (Seek user guide, 2020). It stops at genus or family when unsure. iOS version 2.18.2 released 2026-09-30; Android updated 2026-09-23. No edibility information.

Google Lens is free and fast at giving you a name to look up, but we found no published accuracy test of it on mushrooms (search on 2026-10-31), and it gives no verdict, confidence level or look-alikes.

Local mushroom clubs

The most reliable identification is a person with the whole specimen in hand. The North American Mycological Association lists affiliated clubs by state and province; the British Mycological Society lists local fungus groups. The limit is time: forays are seasonal, and many UK groups record fungi rather than clear them for eating.

Comparison table

Checked on 2026-10-31, US prices. "Edibility on result" comes from the store listing and website, and for Mycoscout from the app itself; a dash means we could not verify it.

Who each option suits

• You found something in the lawn or on a walk and want to know if it is dangerous: an app that leads with the verdict and names look-alikes gives a fast first read; Mycoscout is built for this, and Spore AI positions itself the same way. Treat "edible" as "verify before eating", always. If a child or a dog has eaten it, skip the app and call poison control or your vet (dog ate a mushroom).
• You forage regularly and want a big encyclopedia with maps and a log: Picture Mushroom. Read its trial terms before you start.
• You want to learn, for free, and do not need an edibility answer: iNaturalist.
• You want a free camera that works offline, with no account: Seek.
• You dislike subscriptions and forage in one US region: Shroomify.
• You plan to eat what you find: none of these alone. Join a club, go on a foray, and learn the features a photo cannot show, starting with how to tell if a mushroom is poisonous.

What published tests found

The study everyone cites is Hodgson SE, McKenzie C, May TW and Greene SL, Clinical Toxicology 2023;61(3):166–172 (PubMed, doi 10.1080/15563650.2022.2162917). Researchers at the Victorian Poisons Information Centre and Royal Botanic Gardens Victoria tested Picture Mushroom, Mushroom Identificator and iNaturalist with photographs of 78 specimens sent to the center over 2020–2021, each confirmed by an expert mycologist. From the abstract:

"Picture Mushroom was the most accurate of the three apps and correctly identified 49% (95% CI [0-100]) of specimens, compared with Mushroom Identificator (35% [15-56]) and iNaturalist (35% [0-76]). Picture Mushroom correctly identified 44% of poisonous mushrooms [0-95], compared with Mushroom Identificator (30% [1-58]) and iNaturalist (40% [0-84])."

The death cap "was falsely identified, twice by Picture Mushroom and once by iNaturalist". Conclusion: the apps "are not reliable enough to exclude exposure to potentially poisonous mushrooms when used alone."

The app versions were from 2020–2021 and the confidence intervals are very wide (0–100% for the top result), so the direction is clear and the exact percentages are not. Mycoscout, Spore AI, ShroomID and Shroomify were not tested; we do not claim Mycoscout would score higher. We quote the study because it shows why every app, ours included, should show its uncertainty and send you to a second check.

Best mushroom identification app UK

The apps above are all in the UK stores, priced in pounds; check the local listing. Two things matter more in the UK than the app choice. Names: UK guides say "penny bun" for king bolete or porcini and "field mushroom" for meadow mushroom, so an app that shows the Latin name lets you cross-check with a UK guide; our species pages give both names, for example penny bun and field mushroom. Local groups: the British Mycological Society's local fungus groups run forays in autumn. For the UK's most dangerous confusions, start with death cap vs destroying angel and field mushroom vs yellow stainer.

If you have eaten a wild mushroom and feel unwell, or are not sure whether it was harmful, the NHS says to call 111, or 999 in an emergency (NHS: Poisoning). In the US, Poison Help is 1-800-222-1222, free and 24/7 (America's Poison Centers).

Using any of these apps safely

Photograph the whole mushroom, base dug out, not cut (how to photograph a mushroom). Read the look-alikes, not just the top match. Take a spore print at home; no app can do it for you. Post the find to iNaturalist and wait for a person. Never eat on the strength of an app, a forum answer, or one feature.
