UV Index: Sun & Tan Tracker

Stop guessing when to tan and when to cover up. Real-time UV, sunburn warnings, and a smart timer that tells you exactly how long you can stay out today.

A few minutes too long in the sun ruins a week. This app tells you how long you can stay out today, based on the real UV at your location and your own skin type.

Whether you are heading out for a run, planning a beach day, or chasing your daily dose of vitamin D, the app does the math for you in seconds.

REAL-TIME UV INDEX

• Current UV value for your exact location, refreshed automatically
• Hourly forecast so you can plan workouts, errands, or time outside
• Daily peak so you know when to stay in or cover up
• Saved locations for home, work, and your favorite outdoor spots

PERSONAL SUNBURN TIMER

Tell the app your skin type once. Each time you step into the sun, it calculates your safe-exposure window from the live UV and your personal burn risk. The timer counts down on the lock screen with Live Activities, so you do not have to keep unlocking your phone to check.

TAN SESSIONS AND HISTORY

Log every time you spend in the sun and review your sessions later. See how often you got close to your limit, how often you stayed safe, and how your habits change across the season.

VITAMIN D TRACKING

Get an estimate of how much vitamin D your skin produces during each session, based on UV strength, skin type, exposed body area, and time of day. Sync the estimates to Apple Health if you want them in your wider wellness picture.

SMART ALERTS

• A heads-up before UV is about to peak in your area
• A clear notification when your safe-exposure window is almost over
• Optional reminders to reapply sunscreen during long sessions
• A daily summary of your sun and vitamin D for the day

PRIVATE BY DESIGN

Everything runs on your device. No account, no signup, no email required. Your skin type, session history, and personal data stay on your phone. UV readings are fetched using only your current coordinates and are not tied to any identity.
