SolGlow turns your time outside into the number that matters: vitamin D — measured in IU, not just minutes. And it's automatic: your Apple Watch's daylight is credited to your estimate by itself — no logging, no GPS trail — and every number can show the exact math behind it. From your Time in Daylight, skin type, outfit, age, and your location's sun angle, SolGlow estimates the vitamin D you actually made today — and warns you before you burn. SUN TODAY, IN ONE ANSWER (NEW) • When today's vitamin D window opens — the same UV 3+ hours that call for sun protection • Your burn time, and the protection today's UV calls for: SPF, sunglasses, shade • Optional alerts when today's protection hours begin • Live UV index, one daily goal tuned to your life stage, and vitamin-D foods in your units SUN SAFETY THAT KNOWS YOU (NEW, FREE) • Sun Sensitivity: taking a medicine that can increase sun sensitivity? Every burn time gets a cautious margin • Snow, sand or water bounce extra UV at you — tell SolGlow and today's burn math adjusts • Monthly Skin Check: the ABCDE self-exam with a gentle reminder — a habit, never a diagnosis AUTOMATIC, AND YOU CAN SEE WHY (FREE) • True-D: SolGlow corrects the UV Index for ozone — sunburn UV isn't vitamin-D UV — and shows the cited step whenever it changes your number (Kazantzidis 2009) • Learn & Sources: plain-language guides to UV, sunscreen, winter and more, each with its studies • Ask Siri "How much sun did I get in SolGlow?" — plus Best Sun Window widgets for StandBy, Lock Screen, and Home Screen MADE FOR IPHONE DUO Open it and Today spreads into two columns, guides read like a book, and a live session stands up like a scoreboard on the picnic table. OWN THE WINTER • Winter Mode: when your latitude's noon sun can't make vitamin D, SolGlow shows where yours is coming from — and counts down to the sun's return • Free Winter Countdown widget and Apple Watch complication — works offline • Streak Shield: only physics can excuse a missed day • One-tap supplement check-in from a notification, widget, Siri, or your watch BRING YOUR HISTORY (FREE) • Import your Time in Daylight history from Apple Health in one tap — no account • Back up everything to one file and restore on a new phone SUN SESSIONS (PRO) • Direct Sun: a live burn budget that only counts down, and says plainly when to get out • Live Activity on your Lock Screen and Dynamic Island, with a sunscreen reapply timer • Morning Light, editable history, streaks, a shareable weekly recap — and the Apple Watch app PLAN AHEAD (PRO) • 7-day UV forecast with your personal best-sun windows • Annual sun plan and a jet-lag Trip Planner (timing guidance, not medical advice) KNOW YOUR LEVEL (PRO) • 25(OH)D serum estimate with a 12-week projection • Cofactors, supplement guidance, blood-test reminders, and a doctor-ready PDF/CSV report PRIVATE BY DESIGN No account.
