Watch for the cold.

Your camera turns into a thermal view. A cold spot grows somewhere in the room, a figure rises from it, and you have seconds to turn, keep it in the ring and catch it.

The capture moment: the view flips to white-hot and the figure glows white

Five thermal palettes

Iron, Arctic, Rainbow, White-hot and Black-hot, all included. The room takes the palette's colours and anything cold stands out.

A real hunt

The meter climbs, frost creeps in from the edges, a figure rises from the cold spot. Turn your phone, keep it inside the ring until it locks.

Your Journal

Every catch becomes an entity card with its photo, time and reading. Name the place, add a note, share it.
