Sunlight: UV Index Tracker

Plan outdoor time with current and hourly UV, recorded daylight, reminders, and calm guidance for healthier sunlight habits.

Make sunlight part of a healthier daily rhythm.

Sunlight combines local UV forecasts with your recorded Time in Daylight to help you plan outdoor time, follow your habits, and understand changing conditions throughout the day.

See UV clearly • Check the current UV index, category, temperature, and local conditions. • Follow the hourly UV forecast from morning through sunset. • Read practical sun-safety and UV-protection guidance. • Use your current location or choose a city manually.

Choose a better time outside • Find a preferred outdoor window based on hourly UV and your schedule. • See how conditions change before and after the daily peak. • Set forecast-aware reminders for useful moments.

Record your daylight habit • Read Time in Daylight from Apple Health with your permission. • Start and stop manual outdoor sessions when you need them. • Combine overlapping Health and manual records without double-counting.

Understand your patterns • Review weekly and monthly daylight trends. • Explore timing, consistency, source coverage, and daily evidence. • Follow habit progress and useful context from four Home Screen widgets.

Personal, private, and optional Sunlight does not require an account. Apple Health access is read-only. Manual sessions, preferences, and the optional self-reported skin response profile stay on your device. There are no ads or third-party analytics.

Sunlight Pro unlocks outdoor planning, daylight tracking, personalization, reminders, Trends, and three advanced widgets. Choose monthly access or a one-time lifetime purchase. Both unlock the same Pro features.

Important Sunlight is for general wellness, informational, and planning purposes only. UV forecasts come from Apple Weather. Time in Daylight and manual sessions represent recorded outdoor time, not guaranteed direct sunlight. Personal UV exposure context, skin-response ranges, and Vitamin D sunlight opportunity are qualitative or modeled estimates—not direct sensor measurements, medical advice, diagnoses, treatment, precise Vitamin D production, exact burn timers, or guarantees of safe exposure or safe tanning.
