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.

Refined the dial: the four cardinal hours (0, 6, 12, 18) now sit in bold red markers with clean white numerals in both themes, and the app has a new icon. Thanks for using Clock24h.
