Nightden

Nightden is a calm pocket field guide for anyone who slows down on the trail to look a little closer.

Found a print in the mud or heard something call at dusk? Open Identify, answer a few quick questions about what you noticed, and Nightden narrows the wild down to the animals it could have been.

Explore the Atlas — a curated library of wild animals across North America and Europe. Each species page gathers photos, its range, size, diet, the shape of its tracks and scat, and a recording of its call.

Keep your own Sightings. Log what you spot in seconds: choose the species, add a place, drop in a photo. Your personal Lifelist grows over the seasons, with quiet badges for the milestones along the way.

Open Season to read the rhythm of the wildlife year — what is in rut, what is on the move, what is denning down, and which animals are easiest to find this month.

A beautiful, unhurried place to understand what you meet outdoors.
