Snap it — or pick it
Take a photo right there, or pull one from your gallery. Yesterday's mystery bug counts too.
Insect Identity
Free on iOS & Android
What bug is this? Ask your camera.
Snap a photo — or pick one from your gallery — and the AI inside the app answers in about a second: the species, an honest confidence score, and whether it can actually hurt you. It knows 224 species, it runs entirely on your phone, and it works with no signal at all.

A name, and a straight answer
The species, a confidence score, and a risk badge: harmless, irritates skin, may bite, can sting, or can be dangerous — with first aid when it matters. Most of the time it is harmless, and the app says so plainly.

Then the whole story
Scientific name, size, diet, habitat, when it's active, and the one thing worth knowing — for every one of the 224 species, offline.
The field guide in its head

Not ten thousand obscure taxa. The model is focused on the insects, spiders and ticks people run into at home, in the garden and on the trail.

Honest by design: if you find something rarer, the app gives you its closest common lookalike — with a confidence score low enough to say so. An ID app that's always sure is lying to you.
Private, offline, upfront
An answer with a number on it.
Every identification is a probability, and the app treats you like you can handle that. The best match comes with its confidence score, the runners-up come with theirs, and a blurry photo scores low instead of pretending.
- Photos never leave your phone — the AI lives on the device
- Works in airplane mode, deep woods and basements
- No account, no sign-up, nothing to create
- Free and ad-supported; an optional Pro upgrade removes the ads

Questions
The short answers.
What can it identify?
224 common species across the bugs people actually meet: butterflies, moths, beetles and ladybugs, bees, wasps and hornets, ants, flies and mosquitoes, dragonflies, grasshoppers, crickets and mantises, true bugs and cicadas, household pests like cockroaches, bed bugs and silverfish — plus spiders and ticks. It's tuned to common North American and European species; a rare find may come back as its closest common lookalike, with a low confidence score to match.
How accurate is it?
It never pretends to be certain. Every result is a best match with a confidence score, followed by the runners-up. A sharp, close, well-lit photo usually scores high; a blurry one scores low and the app shows you exactly how low. Treat any result as a strong lead, not a verdict — and never rely on it alone for decisions about stings, bites or eating anything.
Does it work offline?
Yes, completely. The neural network ships inside the app and runs on your phone's own chip. Identification works in airplane mode, deep in a forest, or in a basement. Only the optional ads need a connection.
What happens to my photos?
They stay on your phone. Analysis happens on the device, so the photo is never uploaded anywhere. There is no account and no sign-up.
Why does it show ads?
Ads (via Google AdMob) keep the app free — a small banner and an occasional full-screen ad. On iOS you'll be asked for App Tracking Transparency permission; declining just means the ads aren't personalized.
Does it work on iPad?
Yes — the app supports both iPhone and iPad, and the Android version runs on phones and tablets. The model is identical on every device.
Next time something scuttles by,
you'll have a name for it.
