Clock24h

Shows you how it is.

Clock24h is an honest analog watch face that shows your whole day at a glance.

A single dial wraps a full 24 hours — noon at the top, midnight at the bottom — so the hour hand makes one quiet rotation per day instead of two. The face is split into a light "day" arc and a dark "night" arc, but the seam between them isn't fixed: it tracks your real sunrise and sunset, every day, wherever you are. In summer the light arc swells; in winter it shrinks; near the poles it can fill or empty the whole dial.

Tap the face to switch color schemes. Your selection is remembered.

WHY CLOCK24H

• One full day at a glance — the hour hand sweeps 360° in 24 hours, not 12, so morning, afternoon, evening, and night each get their own quarter of the dial. • A living horizon — the day/night split is computed from your latitude, longitude, and today's date. Midnight sun and polar night are handled gracefully. • Hands that switch color across the seam — the hour and minute hands flip between light and dark as they cross the horizon, so they're always readable on either half. • Tap to change theme — Classic (white day, black night, red accents) or Dusk (warm amber day, slate-blue night, with date and city). Tap again to switch back. Your choice persists. • Reverse-geocoded location — your current city is named on the dial in the Dusk theme, using MapKit. No account, no sign-up. • Yours alone — no tracking, no analytics, no servers. Location is used only to compute sunrise and sunset locally on your watch.

Designed for the Apple Watch screen at full bleed: clean numerals every hour, accent dots at midnight, 06, noon, and 18, a sweeping red second hand, and a smooth Canvas-based render that respects the always-on display.
