A private field journal for people who look closely

Every tiger
you’ve ever met.

Photograph a tiger and WildJournal tells you which tiger — not the species, the individual. Because a tiger’s stripes are a fingerprint: unique, unrepeatable, and yours to read.

The idea

A life list, but of individuals.

Birders keep a life list. Divers keep a log. Nobody keeps one of individuals — because until now you could not reliably tell one tiger from another six months and four hundred photographs later.

WildJournal closes that gap. Every sighting you record is matched against the individuals you have already met. When it recognises one, the sighting joins that animal’s page: the fourth time you have seen her, the second reserve, the year you first found her. When it recognises nobody, that is not a failure — that is a new individual, and the catalogue grows by one.

The journal is yours. It is not a sightings network, not a feed, not a map. One person’s record of the animals they have actually met.

How identification works

Evidence, not a verdict.

WildJournal never asks you to trust a percentage. It shows you the evidence it used: which points on this photograph pair with which points on a photograph you took before, and — the part that actually decides it — which of those pairs agree on one consistent viewpoint. Scrub through the four steps.

Unknown

Twelve corroborating features is the threshold for verified. Below it the result is offered as probable or possible and the judgement stays with you. Unknown is not an error — it is how every new individual begins.

Private by design

The safest place for a tiger’s whereabouts is nowhere.

A journal of rare animals is, handled carelessly, a map for someone who means them harm. So the interesting parts were designed out before anything was built. These are not settings you can toggle on — they are properties of the product.

No coordinates. Ever.: The database has nowhere to put a latitude or a longitude, and the app asks the operating system for no location permission at all. There is nothing to leak, subpoena or sell, because there is nothing there.
Identification runs on your phone.: Matching a photograph to an individual happens on the device, offline, in the field, with no signal. Your photographs are not uploaded to be identified — there is no server that could do it.
A day, not a minute.: Sightings are dated, never clock-stamped. A day is a memory; a minute is a movement track. The record cannot be assembled into the second thing.
No live anything.: No map view, no live feed, no leaderboard, no race to find a named animal first. Deliberate absences, each one written down as a decision, none of them waiting in a backlog.
