## What is Sola?

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. Smarter tanning, safer exposure, fewer regrets.

SCIENCE-BASED UV & VITAMIN D TRACKING
Sola calculates 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 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
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

No guessing. No "just five more minutes." No sudden realization that the sun quietly turned up the heat.

APPLE WATCH, WIDGETS & LIVE ACTIVITIES
Track UV exposure 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 logs UV exposure, vitamin D production, and Time in Daylight directly to Apple Health — accurate data based on real 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)

### 3/5 — I wish I could put in past sessions

*2026-08-18*

I love this app, however there have been several times when I’m in the sun and I either have no signal because I’m paddle boarding or I decide to leave my phone behind. Even though it use to the app doesn’t have a way to put in past sessions so I’m not able to track those sessions.

**Developer response:** EDITED: Thanks for the kind words, and good news: Sola does let you add past sessions. If the session was today, use the Start and End time pickers on the main screen to set the times to earlier today, then save the session normally. For past days, go to History → the ••• icon in the top right → Add a past session. 

And anytime something seems missing, just reach out at support@getsola.com, always happy to help and usually quick. Enjoy the paddle boarding! ☀️ 😎

PS If past paddle boarding sessions log properly now, would love to win you over the rest of the way in terms of the stars 😉

### 5/5 — I paid for premium

*2026-07-24*

The features I wanted were behind a paywall but I paid for them and so far I think it’s worth it. Other apps I tried didn’t have everything I was looking for.

**Developer response:** Thanks a bunch for the five stars and subscribing!! Subscriptions fund development directly, they go straight into the next release (and my list of things to build is longer than I’d like to admit 😉)

If there’s something you want to see in Sola, don’t hesitate to write at support@getsola.com. Again - really appreciate the support! 🙇‍♂️😎

### 5/5 — Detailed & Customizable

*2026-07-09*

The only sun tracker app that has enough detail and customization to actually be useful for Vitamin D. I do burn a little sooner than it says, but it's predictable. I just set my threshold a little lower and it works great. I love being able to see the average vitamin D over the last few months so I can catch myself bed rotting. I don't absorb supplements well so I have to do it old school. This app helps me get enough sun without overdoing it.

**Developer response:** Thanks so much for the 5 stars 🙇‍♂️, glad Sola's helping you optimize how you get vitamin D from the sun. Sun-derived vitamin D lasts longer and also is self-limiting against toxicity in a way supplements aren't. But that has to be balanced against skin damage from UV radiation. That's really the core of what Sola's trying to do: help you hit the sufficiency window without drifting into overexposure.

PS if you don't mind, I'd love it if you emailed me at support@getsola.com with more on the "burn a little sooner than it says" part. I want to understand where the MED estimate and your actual response may be diverging

### 5/5 — Just what I needed for me and my family

*2026-06-15*

I use this app to track the sun exposure for the family in outdoor activities.
Reminders to apply sunscreen and vitamin D tracker is great.
Maybe not what the app was intended for, as I get so bored sunbathing.
The only thing I would add is a family tracker, so I can input the skin type of family members, so we know what exposure other family members that are maybe not old enough to have a phone.

Will try the app for beach days in the near future! I have high hopes.

**Developer response:** Thank you very much for the positive review! 🙇‍♂️ The family profiles idea is genuinely on my radar. Hope the beach days deliver 😉 ☀️ 😎

### 5/5 — Only way I tan outdoors now

*2026-06-12*

I am a v pale girlie. Living in Vegas I was tired of being the palest person I saw anywhere. I used to spray tan weekly but it was messy and got expensive fast.

I happened upon this app while looking up tanning tricks on Reddit. Since using it I am - no joke - 2 shades darker. I have only used it 3 times. 

I decided to splurge and get the paid subscription. It’s worth it to me because I can add in flips with timers. I connect my phone to my speaker for music and the timer goes off through that. 

All in all, great app. I am getting tan without becoming sunburned.

**Developer response:** Thank you so much for the 5 stars! 🙇‍♂️ Glad Sola is working out for you, getting that color without the burn is exactly the app's purpose. Good that you're regularly changing sides, it gives each side a breather, not to mention a more even tan. Enjoy the Vegas sun! 😎 ☀️

### 5/5 — Richtig gut!

*2026-06-01*

Ich habe einige UV-Apps ausprobiert. Diese App ist mit weitem Abstand die beste App, die ich für mich getestet habe. Besonders gut gefällt mir die Integration mit Apple Health, ebenfalls gut sind die vielen Erklärungen, die der Entwickler zur Verfügung stellt. Das und vieles andere habe ich in den anderen Apps vermisst.

**Developer response:** Vielen Dank für Ihr positives Feedback 🙏 Freut mich sehr, dass Sola sich unter den anderen UV-Apps so deutlich abheben konnte 😎 ☀️

### 5/5 — Just excellent

**Developer response:** Thank you so much for your kind review and positive rating🙇‍♂️ Glad Sola is part of your wellness routine up north 🍁🇨🇦❤️

### 5/5 — Actually useful for daily life

*2026-05-20*

I didn’t expect to use this app this often, but it’s honestly become part of my routine now. The design is clean and easy to understand, and I really like how it tells me when it’s a good time to be outside and when I should be more careful with sun exposure.

The reminders feel helpful instead of annoying, and everything just works smoothly. You can tell a lot of thought went into the experience. Definitely one of the better health/lifestyle apps I’ve tried recently.

**Developer response:** Thanks so much for the kind words and the 5 stars! ☀️🙇‍♂️😎

### 5/5 — Helped with my vitamin D deficiency

*2026-05-17, version 3.109*

This app helped me bring my vitamin D levels back to optimal range without the fear of developing skin cancer. Love it!
