The Kagn Field Guide
Everything the app can do, in the order you'll meet it on a real day out — from the first unfamiliar bird call to the lifelist you look back on at home.

First — something moves
Identify it, three ways
However you caught it — a photo, a call, or just a good look — Kagn can put a name to it.
-
Photo identification
Snap any bird, mammal, reptile, insect, plant or fungus and Kagn names it — with a confidence score, alternative candidates for the tricky ones, and a full field-guide entry one tap away. Distant, low-light shots often work better than you'd expect.

Sound identification
Heard it but never saw it? Record a few seconds of birdsong and Kagn suggests the singers.

Describe it, or ask anything
"Small brown bird, red chest, hopping on the lawn" — chat identification works from a description alone. And on any species page, Ask the Guide answers follow-up questions: what it eats, where it nests, how to tell it from its lookalike.

Then — make it yours
Log it once, keep it everywhere
A sighting in Kagn isn't a photo in a camera roll — it's a record that organises itself.
-
Regional and world packs
Field guides built for where you are — the UK, Australia, North America, Southern Africa, Thailand and more — plus world packs that cover every species on Earth. Every pack is on every account; free and paid differ only in daily AI identifications.
Browse the packs -
One sighting, every pack
Log a robin in the UK pack and it's automatically in World Birds too — and in any other pack it belongs to. Regions populate across packs by themselves; you never file anything twice.
-
Log it with photos, video & sound
A sighting can carry the whole moment: photos, short video clips, and sound recordings — plus written notes, location and count.
-
Lifelist & trips
Every species you've ever seen, with all that media attached, grouped into trips. First-ever finds get their gold lifer moment; repeat sightings collapse tidily so the list stays readable.
Out of signal — keep going
Built for the places wildlife actually lives
Reserves, valleys, coastlines — the best spots rarely have bars of signal. Kagn plans for that.
-
Offline field logging
Open a regional pack while you still have a connection and it quietly readies itself for the field. Out of signal, you can keep logging: search species by name, or save a find as unknown with its photo — when you're back in coverage, Kagn identifies the unknowns and syncs everything home.
-
Field Companion
Back in signal, ask "what's around me right now?" — Field Companion shows what other spotters are finding near you today.
Back home — the long game
A community that checks your work
-
