What the endangered species apps actually do

No app tracks the conservation status of endangered species. The record that does is a website: the International Union for Conservation of Nature's Red List, whose July 2026 update covered 175,909 species, 49,505 of them threatened with extinction. What an app store returns for that search is three different kinds of thing — identification tools that name what is in front of you, showcases built to introduce a handful of animals, and fundraising products. Each is good at something. None of them is a tracker, and it is worth knowing which one you are installing.

The one most people find first

WWF Together is published by World Wildlife Fund and listed free in the Education category. Its App Store description promises interactive stories for five endangered animals — giant pandas, tigers, monarch butterflies, sea turtles and polar bears — with further species reachable through an interactive 3D globe.

The same listing records the last update as version 3.0.3, on 10 February 2021.

That is not a complaint about the work, which was ambitious for its moment. It is a description of what you are getting: a showcase built at one point in time, not a record kept up since. A story about the monarch butterfly assembled five years ago is a story about the monarch butterfly of five years ago.

The ones doing steady work

Seek and iNaturalist come from the same organisation and are both free. They answer a different question, and answer it well.

Seek points the camera at a living thing and tells you what it is. Its listing states that the app does not require registration and does not collect user data by default, and that while it asks for location, that location is obscured — precise location is never stored in the app or sent to iNaturalist unless you sign in and submit an observation. For an app aimed at families, those are the two sentences worth reading.

iNaturalist proper is the opposite trade, made deliberately. You create an account, your observations go into a public dataset, and the stated point of the exchange is contributing to science. Its classic app was last updated on 6 September 2025, and its own listing now directs people to a redesigned version.

Neither tells you whether a species is in trouble. They tell you what you are looking at, which is a different question and a better-answered one.

The fundraising ones

Symbolic adoptions, streak-shaped giving, animal-themed games. These are fundraising and entertainment, and there is nothing wrong with either. The failure mode is only ever mistaking one for the other: an adoption certificate is a receipt for a donation, not a status report on an animal, and no app has ever produced a conservation outcome by being opened.

Two questions before you install anything

- Does it date its numbers? A population figure without the year it was measured is decoration. So is a category quoted without the assessment behind it — what a category does and does not tell you, and what a count is actually counting, are the two things most of these apps skip. - What does it want from you? An account, a location, an email address, a payment, or nothing. Every one of those is defensible. Being unable to tell which applies, before installing, is not.

Where this site sits

Witness, which publishes these notes, is an iOS archive of thirty species. Each record names its sources and the date each was checked, the same way the archive does on the web. It is not an identification tool and it does not tell you what is outside your window.

It asks for money too, and by the standard above it should say so plainly: parts of it are paid, as in-app purchases handled by Apple. The featured species, its sources, the act of witnessing and a private reflection are intended to stay free. A Witness records attention. It does not save anything, and no app on this page does either.
