Tan Timer & UV Index - Sunlit

Sunlit is the tanning app that turns sunshine into a plan. Check the live UV index, discover your skin type, get a personalized tanning time and start a guided tan timer that tells you when to flip, when to reapply sunscreen and when to head for the shade. Tan smarter, avoid sunburn and track the vitamin D you earn from every session.

LIVE UV INDEX & 10-DAY UV FORECAST
• Real-time UV index, temperature, sunrise and sunset for your location
• 10-day UV forecast so you can plan beach days, pool days and holidays ahead
• Hour-by-hour UV levels to spot the safest and most effective time to sunbathe
• Clear sun safety guidance for low, moderate, high and extreme UV

KNOW YOUR SKIN TYPE
Everyone tans differently. Sunlit identifies your Fitzpatrick skin type with a few quick questions or an AI skin scan from a photo. Your skin type, sunscreen SPF, tanning goal and how much skin you expose all shape your personal recommendation.

PERSONAL TANNING TIME & BURN TIME
• Calculates how long you can safely stay in the sun today
• Estimates your burn time so you never guess again
• Adjusts for SPF, cloud cover and current UV intensity
• Finds the best tanning window of the day for your skin

GUIDED TAN TIMER
Start a tanning session and let Sunlit take care of the details:
• Countdown timer based on your skin type and the live UV index
• Position-change reminders for an even, all-over tan
• Sunscreen reapplication alerts so you stay protected
• Session end alerts before you reach your burn limit

SUNBURN PROTECTION, BUILT IN
Sunlit is a sunburn app as much as a tanning app. Sunscreen reminders, burn-time estimates and UV alerts help you build a natural, golden tan gradually instead of paying for it with red, peeling skin.

VITAMIN D TRACKER
Sunshine is your best source of vitamin D. Sunlit logs every tanning session and estimates the vitamin D you produce from sun exposure, plus any supplements you take, so you can see your progress over days and weeks.

TANNING LOG & PROGRESS
• History of every sunbathing session with duration and UV level
• Weekly and monthly tanning time at a glance
• Track your tan progress toward your goal

PERFECT FOR
• Sunbathers who want a natural tan without the burn
• Beach, pool and holiday planning with a UV forecast
• Fair skin that burns easily and needs a precise sun timer
• Anyone curious about sun exposure and vitamin D levels
