## UV Index Description
Most UV apps show you a number. UVSiesta tells you what that number means for your skin, today, in minutes.

Six quick questions work out your Fitzpatrick skin type. Add your age, the SPF you actually use and what you are wearing, and every figure in the app is computed for you instead of read off a generic table.

Above the 49th parallel that matters twice over: for months of the year the sun never climbs high enough to make vitamin D at all, and UVSiesta tells you plainly when today is one of those days rather than sending you outside for nothing.

YOUR NUMBERS, NOT AVERAGES
• Burn time in minutes for your skin, your SPF and today's UV
• The exact minutes of sun that reach your daily vitamin D target, in IU
• A narrow personal sun window — 12:45–13:10, not "sometime between 10 and 4"
• Real cloud attenuation measured against clear-sky UV, so an overcast day changes the plan instead of adding a disclaimer

BUILD THE HABIT, FREE
• Log sun time in two taps. No timer, no subscription
• Streak, daily progress ring and full history
• A morning brief with today's real numbers
• Live UV index, the hourly curve and today's peak

PREMIUM
• Guided vitamin D and tanning sessions with turn-over reminders
• A 14-day Tan Plan that adapts to the tolerance you have actually built
• 7-day sun planner
• Clinical vitamin D: enter your 25(OH)D blood result for a personal target and a 12-week projection
• UV for any location worldwide
• Ideal-window and tan-plan notifications

WHEREVER YOU LOOK
Home and Lock Screen widgets, a Live Activity on the Dynamic Island while a session runs, and an Apple Watch app with complications — all reading the same personal numbers.

BUILT ON PUBLISHED SCIENCE
Exposure is weighted by the UVB response curve rather than a flat elevation threshold, doses are integrated across the hours you are actually outside, and every recommendation is capped at a safe ceiling for your skin type. 28 peer-reviewed references are cited in the app.

UVSiesta gives estimates to support healthy sun habits. It does not diagnose or treat anything and does not replace medical advice. If you have a skin condition, take photosensitizing medication, or are managing a vitamin D deficiency, talk to your doctor.

Premium is an auto-renewing subscription. The price and duration are shown before you buy. Payment is charged to your Apple Account, and it renews unless you cancel at least 24 hours before the period ends. Manage or cancel in your Apple Account settings.
