UV Index Now - Sunhalo

Sunhalo tells you the one thing your weather app won't: when to get out of the sun.

Set your skin type once. Sunhalo combines it with the live UV index where you're standing and the SPF you're actually wearing, then reminds you when to reapply, when to take shade, and when to reassess your time outdoors.

Built for people who love the sun and respect it.

YOUR PROTECTION PLAN • Live UV index and hourly forecast for your exact location • A personal reassessment estimate from your skin response, live UV, and labeled SPF • Session coaching: turn reminders, reapplication prompts, and shade breaks • Lock Screen countdown, so it keeps running while your phone is in your bag • Conservative by design, and capped at two hours

FIND THE SUN • A live compass showing exactly where the sun sits right now • Morning and evening golden hour windows • Which way to face for even exposure

VITAMIN D, WITHOUT GUESSWORK • Estimates IU from every outdoor session, factoring in skin type, exposed skin, SPF, and UV • Daily goal and weekly totals at a glance • Log incidental sun in seconds

TRACK YOUR SUN DAYS • Private journal with photos that never leave your device • History across week, month, and year • A product locker for the sunscreens you actually use

WIDGETS AND LIVE ACTIVITIES • UV index and today's protection window on your Home Screen • Golden hour widget with face direction • Live session countdown on your Lock Screen

HONEST BY DESIGN Any tan is a sign of UV damage, and Sunhalo never pretends otherwise. No base-tan myths, no advice to burn for beauty. Just live data, clear reminders, and a Learn section that tells you what the research actually says.

Sunhalo gives educational estimates, not medical advice, and it is not a medical device. It cannot measure your skin or guarantee safe exposure. Medications, altitude, reflection off water, sand, or snow, and how much sunscreen you actually apply all change your real risk. When in doubt, choose shade.

SUNHALO PRO An optional subscription unlocks the vitamin D tracker, Sun Seeker compass, journal, history, and Lock Screen Live Activities. Live UV, the protection timer, and session coaching are always free.

Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple ID settings.
