About
LightKing is a daylight closer. Your Apple Watch already measures Time in Daylight. We ping you when today's pace is slipping, while you still have time to get outside.
HOW IT WORKS
Set a daily daylight goal, reminder fequency, and a light window (default 30 minutes, 8:00 to 18:00). LightKing monitors Time in Daylight from Apple Health. We never write samples and we never upload your minutes. If you fall behind, you get a ping with enough time to get outside.
*RECENT APPLE WATCH REQUIRED
Time in Daylight comes from Apple Watch (SE 2, Series 6, or Ultra). iPhone cannot measure this. No Watch means an empty day. Allow Health, Notifications, and Background App Refresh.
FREE AND PRO
Free: Progress, morning motivation, celebrations, and 3 Rescue Ping days that count only when they work.
Pro: Unlimited behind-pace pings. Try it free for 7 days. Cancel anytime in App Store subscriptions.
Your daylight time stays on your device.
