A contemplative 24-hour clock. Sun arcs, twilight bands, moon phases. Happy March equinox! Your day has a shape. Sloww shows it to you. Instead of hours and minutes, Sloww draws your whole day as a 24-hour clock — where the sun is right now, when twilight starts, what the moon is doing. It's a different way to see time: slower, wider, and grounded in the sky above you. 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 — full, crescent, new — updating as the cycle turns. 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. 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. WIDGETS Three Home Screen sizes and eight Lock Screen widgets. 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. 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.
