Sloww: Sun & Moon Phase Clock

DESIGNED FOR PRIVACY

Your location is used only for astronomical calculations and never leaves your device. No analytics. No ads. No tracking. No subscriptions. One purchase, everything included.

SUN RING & TWILIGHT

A golden arc traces your daylight from sunrise to sunset. Around it, colored bands show the three stages of twilight and golden hour. You can see at a glance how much light is left, when dusk begins, and how your day changes with the seasons.

MOON RING & PHASE

An inner ring tracks the moon across your sky. The icon shows tonight's phase, whether full, crescent, or new. Moonrise and moonset times appear in the readout below.

LUNAR CYCLE & YEAR RING

Two delicate rings track the 29.5-day lunar cycle and the year's progress. Solstices, equinoxes, and where you are right now, all at a glance.

BREATHING EXERCISES

The innermost ring guides calming breathing patterns: box breathing, coherent breathing, 4-7-8 relaxation, and extended exhale. A small moment of stillness, whenever you need it.

APPLE WATCH

The full Sloww clock comes to your wrist — the same sun, moon, and twilight rings, drawn from your watch's own location, with Always-On so the sky stays glanceable. Two complications bring it to your watch face, too: Sloww Sun shows the sun's arc through the day and the next light event; Sloww Moon shows tonight's phase with moonrise and moonset. Four families each, from corner to rectangular.

NIGHT MODE

After sunset, the clock warms to a dark palette that preserves your dark-adapted eyes. An optional mono-red mode keeps your night vision fully intact.

CELESTIAL BELLS

A gentle vibration or notification at sunrise, sunset, golden hour, moonrise, and more. Per-event escalation and configurable lead times.

SUNSET LIVE ACTIVITY

A lock screen countdown from golden hour through civil twilight, with a segmented progress bar and phase labels.

ASK SIRI

Ask about sunrise, sunset, moon phase, or the shape of your day. Seventeen voice intents in a warm, literary register. Also available in the Shortcuts app.

SAVED LOCATIONS

Search any city or enter exact coordinates. Bookmark your favorites and see what daylight looks like on the other side of the world. The clock works beautifully at every latitude, from the equator to the midnight sun.

MADE FOR IPAD

A native iPad layout lets the clock grow to fill the screen. Landscape places the clock and readout side by side, with pointer and trackpad support throughout.

WIDGETS

Three Home Screen sizes, five Lock Screen widgets, and three StandBy widgets for bedside viewing. Sunrise, sunset, moon phase, daylight remaining, and more. Always a glance away.

READOUT

Below the clock, a rich readout shows sunrise, sunset, moonrise, moonset, day length, and more. Tap to cycle through display formats: 12-hour, 24-hour, spoken time, and period of day.

CUSTOMIZATION

Four color palettes in light and dark modes. Colorblind-safe filters for red-green and blue-yellow vision. VoiceOver support with full clock descriptions and spoken labels on every control.
