About Skein: Nature ID & Food Webs
Point your camera at any plant, animal, bird, bug, or fungus and Skein tells you exactly what it is in seconds. Then it does something no other ID app does: it shows you how that species connects to everything else alive around you. There has never been an app quite like Katch. Anything can name a species. Skein captures what they DO together, who eats who, who pollinates what, who lives on whom, and turns your finds into a living web only you have witnessed. IDENTIFY ANYTHING, INSTANTLY Snap a photo and get an answer in seconds, with a confidence score and the science to back it up. Plants, animals, birds, insects, fungi. If it is alive, Skein will have a go. You can even identify birds, frogs, and insects by their sound. SEE HOW LIFE CONNECTS Snap what you see, then snap what it interacts with, and Skein records the connection: a bee on a flower, a bird taking a berry, a spider and its prey. Each one becomes an edge in your food web. You are not just collecting creatures. You are mapping the living relationships around you. BUILD A LIVING FOOD WEB Every creature you catch takes its place in a food web that grows as you explore. See the trophic levels, the predators and pollinators, and the gaps still waiting to be witnessed, verified by the community. CHASE RARE FINDS AND RARE MOMENTS Every catch is scored across seven rarity tiers. And the rarest thing of all is not a species, it is catching two of them in the act of interacting. EXPLORE A LIVING WORLD MAP See what other naturalists are finding and connecting near you and around the world. JOIN A COMMUNITY OF NATURALISTS Share your best finds, help verify the interactions others log, and build the real map of how life fits together. FREE AND UNLIMITED Identifying is free with no daily limit. Collect, connect, and grow your web every day. Skein Pro goes deeper: the full depth of your food web and one-scan multi-species scenes, with no ads, ever. Try it free for 14 days. Start your web today with Skein.

What’s new
Version 2.0.0 · Updated September 24, 2026
Skein is here. Katch is now Skein, with a warmer new look throughout. The Community feed is now alive, with every catch appearing so there's always something new to explore. When you Verify a find, you'll see where the photo was taken on a map, making tricky IDs easier to call. Prefer to stay private? Your catches still appear in the feed, but anonymously as "Anon" with no name or location shown. We've also renamed Judge to Verify and polished wording throughout.
