WristSun

Plan one shoot in a complete morning or evening golden-light window on Apple Watch. Choose coordinates, an IANA time zone and a date. Open a golden event, set shooting time (5–60 minutes) and your own preparation reserve (0–60 minutes), in 5-minute steps. See whether preparation and the full shoot still fit, plus the latest preparation and shoot-start times. Preparation is your estimate, not a route or arrival prediction. Explicitly save one independent plan on the watch. Replacing it needs confirmation. Reopen to see the same place, date, window and durations; Home, Today, language and watch time-zone changes do not retarget it. Progress refreshes while the app is open. There are no background alerts. Plans require complete start and end boundaries within the selected local date; partial or polar light may still exist when planning is unavailable. Also browse sunrise, sunset and golden/blue event details. Location is optional; manual coordinates and offline presets work without a phone companion or network. You select the time zone. English and Simplified Chinese are available. Times are astronomical estimates, not weather or guaranteed usable light. Sunrise/sunset use solar centre −0.833°; golden −4° to +6°, blue −6° to −4° are this app’s photography conventions. Clouds, terrain and altitude affect visible light; very brief polar crossings may escape five-minute sampling. Dates and UTC offsets distinguish daylight-saving transitions. No account, backend, ads, analytics or location uploads. Settings and the active photo plan are stored locally; a previous valid plan may be retained for recovery.
