Built for the moment you find something

Usually crouched in a garden, holding a phone in one hand, with no idea whether the thing in front of you is dangerous.

Identify by photo

7,681 species, recognised on the phone itself. You get a ranked shortlist with a confidence you can argue with, never a single confident-looking guess.

Spiders included

Most insect apps answer a spider with the least-unlike insect they know. This one can tell the difference.

Is it dangerous?

Every result says whether the species bites, stings, or is harmless — and says plainly when there is no reliable data.

Identify by sound

Record a cricket, katydid or cicada singing and hear back which one it was.

An encyclopedia to browse

Search or wander by group — butterflies, beetles, bees, dragonflies, spiders — with photographs and taxonomy from iNaturalist.

Keep a collection

Save species you would like to meet. Identify one and it is marked as found.

Three steps

The same three the app walks you through on first launch.

01

Photograph it

One photo, or a recording if it is singing. Nothing is uploaded for photo identification.

02

Read the answer

Name, taxonomy, whether it is dangerous, and how sure the app actually is.

03

Keep it

Every find is saved to your collection, with the photograph you took.
