About

Nature Flip Clock

Features
Read full description

A flip clock where butterflies, birds, leaves and flowers gather into every digit. Each digit sits on its own card. When the minute changes, the card flips down and new specimens fly in, landing just as the flip ends. Put it on your nightstand or desk: the screen stays on while Horae is open. Prefer digits without cards? Turn off Flip clock in Settings. FIVE FACES • Butterflies — free; wings gather along the strokes of each digit • Birds — birds perch where the strokes run • Pebbles — river stones worn smooth, quiet and heavy • Fallen Leaves — autumn leaves settle into the hour • Flower Clock — Linnaeus's flower clock of 1751: twelve flowers that open at their own hours, and a firefly that keeps the seconds MADE FOR THE NIGHTSTAND • Flip clock — on by default, with a live preview in Settings • OLED screen protection — the digits drift slowly to prevent burn-in • Swipe up or down on the clock to adjust brightness • A dark face that is easy on the eyes at night QUIET BY DESIGN No ads, no accounts, no analytics. The clock works fully offline. Butterflies is free, with every feature, flip clock included. One purchase unlocks the other four faces and every face added later. Named for the Horae, the Greek goddesses of the hours.
