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.

Sola is a WIN from a dev that cares
iOSgreg
Out of testing 8 different free and paid sunlight apps, this one, Sola, is the winner. It brings helpful, tailored information for me to understand how to optimize my sun exposure, while paying close attention to health effects from UV.What it brings: detailed data and graphical analysis, syncs with Apple Health, has multiple widget options for your screens, Apple Watch compatibility, and even vitamin d tracking from nutrition.While Sola has a lot of use for anyone who wants to safely tan their skin, I primarily use the app to track my Time in Daylight and help my body regulate circadian rhythm. Being outdoors and sunlight exposure have significant effects on mental health, and I use this app to tell me when it’s a good vs bad time to go outside to improve my mood. What’s really nice is that Sola also sends me safety notifications on UV exposure, a feature I used a lot over a weekend trip to maximize my time outside without getting burned.As a final note, it’s clear from the attention to detail and how frequently this app is updated that the Developer cares about this app, which is another plus in looking for a sunlight app I can use and count on for the long term.

Great Tanning App!!!

This app has really improved over the years and really happy that it calculates Vit D3 generation. Would really like to suggest that the session includes a “pause” and “continue” button. Also, a different alert sound would be nice to have when the session is over/need for applying more sun block when you’re using or not using the flip notification alerts…maybe a short burst of seagull calling sound for more sunblock applications and a longer burst for the end of the session? Thanks!
Developer Response
Thank you for updating your review, I really appreciate it! I've recently been focused on refactoring Sola’s widgets, but I’m getting close to tackling improvements to the timer, including pause/resume functionality and customizable alert sounds. Thanks so much for your patience! 😊__________________________Thank you so much for the 5-star rating and thoughtful feedback! Glad to hear the app has been helpful and that you’re enjoying the Vitamin D3 tracking feature. The enhancements you mentioned are already on the roadmap :) If you have any further ideas or questions, would love to hear from you anytime at support@getsola.com
Amazing experience

Have used this for a year and I was the tannest I had ever been last year! I never burned when I listened to the app. So nice to know I can go out and get my vitamin D and a little sun in just a few minutes during the height of summer, and I didn’t have to sunscreen up! Looking forward to working on my tan again this year, and making sure I get that daily Vitamin D!
