UV Index & Tan Timer: Sunwell
Sunscreen Reminder & UV Alerts
Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
Know your sun. Sunwell turns live UV into personal guidance: safe time for your skin, tan session timers, reapply reminders, and the best beaches nearby.
Stop guessing. Start glowing.
Sunwell is the only app that turns live UV data into a personal game plan for your skin, telling you exactly when to step outside, how long to stay, and how to come back with a tan instead of a burn.
Whether you're chasing a sun-kissed glow, protecting sensitive skin, or simply trying to hit your daily vitamin D target, Sunwell delivers the precision that generic UV trackers never could.
YOUR SKIN. YOUR PLAN.
Everyone burns at a different rate. Sunwell learns your Fitzpatrick skin type and the SPF you're wearing, then calculates your personalized burn time down to the minute. No more wondering "am I okay out here?" You'll know exactly where you stand.
LIVE UV INTELLIGENCE
Sunwell pulls real-time UV index data adjusted for your local cloud cover and altitude, so the number you see reflects the actual UV reaching your skin right now, not a generic regional estimate: an hourly forecast and multi-day UV outlook surface peak-UV windows and golden-hour opportunities before you ever step outside.
TAN SMART, NOT HARD
The built-in tanning timer shows your optimal exposure window. The sweet spot between getting colour and risking damage. Your daily MED (Minimal Erythemal Dose) budget tracks exactly how much sun you've banked across sessions, so you always know when you're approaching your safe limit and can plan accordingly.
VITAMIN D, TRACKED
Sunwell estimates the vitamin D your body synthesizes from each session and logs it automatically to Apple Health. It's the effortless way to make sure you're getting the sun your body needs, without the guesswork or the overexposure.
ALWAYS-ON REMINDERS
Smart notifications remind you to reapply sunscreen before it wears off, alert you when peak UV is approaching, and ping you the moment your optimal tanning window opens or closes. Your skin stays protected even when your attention is elsewhere.
AT A GLANCE, EVERY TIME
Home screen widgets, a Lock Screen Live Activity, and a full Apple Watch companion keep your burn countdown, UV index, and safe-dose progress visible without ever opening the app. Everything you need, always one glance away.
YOUR SUN HISTORY
Session tracking and weekly analytics show how your sun exposure builds over time, a powerful way to stay accountable to your skin, your goals, and your long-term health.
Sunwell Premium unlocks the full coaching experience: personalized burn-time plans, MED tracking, vitamin D logging, smart reminders, widgets, and the Watch app. Choose a simple monthly plan, or save with the yearly plan, which includes a 7-day free trial.
Tan with intention. Glow without regret.
