Sola: UV Index & Sun Exposure

Smart tanning & sunburn alerts

Free · In‑App Purchases

Sunlight enhances mood, relieves stress, improves sleep, and triggers essential vitamin D production. But too much sun exposure increases the chances of sunburns and skin cancer. MEET SOLA: YOUR ULTIMATE SUN EXPOSURE & VITAMIN D TRACKER Whether you're aiming to safely achieve a perfect suntan, get vitamin D without sunburn, or minimize UV radiation exposure, Sola is the app for you. Sola calculates and monitors your sun exposure and vitamin D production based on the current UV index forecast, your skin type, existing tan, previous exposure, sunscreen SPF, and whether you change sides regularly when you sunbathe. AUTO-TRACKING SUN UV SESSIONS If you have an Apple Watch with ambient light sensor, Sola can automatically detect your outdoor sun exposure leveraging Time in Daylight data from the Health app. CONVENIENT REMINDERS With Sola’s handy timer, you’ll never forget to reapply sunscreen, flip over for an even tan, or know when it’s time to seek shade. APPLE WATCH INTEGRATION It also comes with an Apple Watch extension so that you can manage your UV exposure right on your wrist. WIDGETS AND LIVE ACTIVITIES For users on iOS 17 and above, Sola offers Widgets that provide real-time updates on the current UV index, your received UV dose, sunlight-triggered Vitamin D, and an estimate of Safe Suntime. Additionally, Live Activities bring Sola's active Timer data right to your Lock Screen and Dynamic Island for seamless tracking. HEALTH APP INTEGRATION Sola seamlessly integrates with the Apple Health app to track your vitamin D production, UV index exposure, and, if available, Time in Daylight to get more accurate UV dose and vitamin D levels based on actual daylight conditions. SUNLIGHT FRIENDLY DESIGN Lastly, thanks to its monochrome themes, you can easily interact with the app in bright sunlight, and especially if you are wearing sunglasses. DOWNLOAD SOLA NOW Enjoy a FREE first week, and make the most of your time in the sun! After the free trial, all access can be unlocked with an annual subscription.
