Sola: UV Index & Sun Exposure

UV dose & vitamin D tracker

Free · In‑App Purchases

SUNLIGHT: FRIEND OR FOE? Sunlight can boost your mood, lower stress, improve sleep, and kick-start vitamin D production. It can also turn you into a walking tomato and increase your risk of skin cancer. Like most powerful forces in the universe, moderation is key. MEET SOLA: YOUR PERSONAL POCKET SUN-NERD Whether you’re chasing a golden glow, hunting for Vitamin D, or hiding from UV rays like a vampire, Sola helps you enjoy the sun without burning. Unlike basic UV apps, Sola tracks your real UV dose over time, not just the current UV index. That means smarter tanning, safer exposure, and fewer regrets later. SCIENCE-BASED UV & VITAMIN D TRACKING Sola calculates and tracks your sun exposure using real science, including: • Current UV index forecasts • Your skin type and existing tan • Past sun exposure (yes, it remembers) • Sunscreen SPF • Whether you actually flip over like a pancake instead of roasting one side All of this feeds into your accumulated UV dose and estimated vitamin D production, so you know when enough is enough. AUTO-TRACKING WITH APPLE WATCH If you wear an Apple Watch with an ambient light sensor, Sola can automatically detect when you step outside using Time in Daylight data. You don’t even have to open the app. It just knows. Not in a creepy way. Promise. REMINDERS THAT SAVE YOUR SKIN Sola’s built-in alerts remind you when to: • Reapply sunscreen • Flip for an even tan • Seek shade before you cook • Get notified when the UV Index reaches, exceeds, or drops below your chosen threshold so you’re not blindsided by a surprise UV spike No guessing. No “I’ll just stay five more minutes.” No sudden realization that the sun quietly turned up the heat. APPLE WATCH, WIDGETS & LIVE ACTIVITIES Track your UV exposure straight from your wrist (because pulling out your phone mid-sunbath is how sand gets everywhere). Sola widgets show: • Current UV index • Accumulated UV dose & sun-triggered Vitamin D • Estimated safe sun time • Time-in-Daylight stats Live Activities keep your session timer on the Lock Screen and Dynamic Island, so you can see exactly how close you are to crispy. APPLE HEALTH INTEGRATION Sola integrates with Apple Health to log UV exposure, vitamin D production, and (when available) Time in Daylight. That means more accurate data based on actual sunlight and real science, not guesswork. DESIGNED FOR ACTUAL SUNLIGHT High-contrast monochrome themes make Sola readable even in blinding sunlight: yes, even with sunglasses on. No squinting required. Save the crow’s feet for later. TRY SOLA Some basic features are free. Unlock everything with a free 3-day trial, then continue with an annual subscription; or grab a one-time lifetime purchase, because unlike a summer fling, commitment can be beautiful. “A sunburn-free world, one Sola user at a time.“ ~ Dr. Helios (probably) DISCLAIMER (THE BORING BUT IMPORTANT PART) Sola provides informational estimates about sun exposure and UV radiation based on scientific research and available data, including skin type, location, UV intensity, sunscreen use, and related factors.
