Gnomon — Golden Hour & Light
Sun times on your Lock Screen
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Know when the good light lands today: one band from night through golden hour, with a marker on now. That band is free forever and works offline anywhere on Earth.
Gnomon puts today's light on your Lock Screen: golden hour, blue hour, sunrise and sunset for any spot — computed on your iPhone, never from a server.
The day is drawn as one readable band of light — night, blue hour, golden hour, day — with a marker showing exactly where you are in it. Add the widget once and the answer to "when is the light?" is simply there, the way the time is there. Before an evening that matters, start a quiet Live Activity and watch the countdown to golden hour on your Lock Screen and Dynamic Island.
What Gnomon does:
- Computes sun and moon times with standard astronomical algorithms (NOAA/Meeus), entirely on your device — it works in airplane mode, anywhere on Earth
- Shows today's light as a Lock Screen widget, a Home Screen widget, and a golden-hour Live Activity countdown
- Plans ahead with a month light-calendar: see golden hour drift through the season, with moon rise and set lines for photographers (Gnomon Pro)
What Gnomon never does:
- Guess. There are no sunset-quality scores and no forecasts — only exact, computed times
- Send your location anywhere. Gnomon has no server, no account, no analytics
- Nag you. No streaks, no notification spam — the only alert is the Live Activity you asked for
The free version is complete for where you are right now: the full day card and the Lock Screen widget for your current location, forever. Gnomon Pro adds saved spots, scheduled Live Activities, and the month light-calendar.
