Sun Nudge is your gentle daily reminder to get more natural daylight — without the hassle. It reads Time in Daylight from Apple Health. No timers to start. No account to create. Just a clear picture of today’s light on iPhone and Apple Watch. What’s new in 1.1 Sun walks When daylight and steps overlap, Sun Nudge glues those windows into a sun walk — minutes, distance, and the time it happened. You’ll also see what share of your steps were outside. When the sun happened A morning, midday, and evening strip so you can tell if your light was a sunrise walk or a late-afternoon stretch. Morning light A quiet streak for days whose first daylight is before a time you pick. Week at a glance Seven checks for the days you hit your goal, plus a month you can scroll back through. Still here, still calm • Daily daylight ring and streak • A goal you can change anytime • Sunscreen logging and reapply nudges (estimates only — not medical advice) • Optional UV and golden hours when you turn on location • Home Screen and Lock Screen widgets, Control Center, and Shortcuts • Apple Watch pages for today, this week, your walk, and sun safety Privacy, on purpose Sun Nudge has no account and no ads. Time in Daylight, steps, and walking distance stay on this device. Location is optional and only used for UV and sky when you ask for sun safety. Automatic daylight minutes come from Apple Watch via Apple Health. Allow Steps and Walking + Running Distance if you want sun walks; Time in Daylight still works without them. Step into the light. Feel the difference.
