SunDeck presents a daylight-planning iPhone app that scores upcoming sunsets and adds sun-path, shadow, alarm, and golden-hour tools.

Landing page captured for the 2026-09-29 issue.

For: Sunset chasers and daylight planners
Worth noticing: The page shows a Los Angeles sunset demo scored 89, with a plain-language reason and a confidence indicator.

Field notes

The homepage includes a browser-computed Los Angeles example and explains the forecast in terms of cloud geometry at the horizon. The planned iPhone feature set includes a draggable sun dial, AR and virtual-sky views, building shadows based on OpenStreetMap footprints, and alarms that adjust with seasonal changes. The site says solar geometry is computed on-device and that location does not leave the iPhone.
