A field day's photographs, filed by species.

Point PlumageSort at a folder. It identifies the birds and sorts them into folders named for the species — on your own Mac, with no upload, no account and no network connection.

What it actually does

And, as importantly, what it declines to do

3,439 species

1,040 of them recorded in the Indian subcontinent. Tell it where you were shooting and it stops offering you American birds.

It says when it doesn't know

Anything it isn't confident about goes to _Uncertain rather than being guessed at. Measured on 391 photographs of 20 species it has never seen, the strictest of the three settings keeps 89% of them out of your species folders.

Nothing leaves your Mac

Identification runs on Apple's on-device machine learning. There is no server to send photographs to, which is also why it works in the field with no signal.

The trial counts birds

Forty frames of the same bird spend one of your ten free species, not forty. Paid photographs are counted per frame, and a RAW and JPEG of one shot count as one.

Photographs

Bought outright. No subscription, and they never expire

Try it first: 10 species free, no card and no account. Ten different birds — a burst of forty frames of one bird spends one of the ten, not forty.

Bought inside the app

Photographs are bought once and never expire. There is nothing to subscribe to, nothing to cancel and nothing to keep an eye on — buy a batch when you need one, and it waits until you do. Inside the app you can also buy any amount from ₹99.

A licence covers one machine, and you can move it to another whenever you like from inside the app. A photograph is one press of the shutter, so 500 means 500. A RAW and a JPEG of the same shot count as one; a photograph the app cannot confidently name still counts, because the work of looking at it was done either way.
