Sunlight enhances your mood, relieves stress, improves sleep, and triggers vitamin D production. But too much sun exposure increases your chances of sunburns and skin cancer.

Sola calculates and tracks how much sun exposure you are getting based on current UV index forecast, your skin type, any existing tan, sunscreen SPF, and whether you change sides regularly when you sunbathe.

Sola features a convenient Timer that reminds you when to re-apply sunscreen, when to flip over if applicable, and when you need to get out of the sun.

It also comes with an Apple Watch extension so that you can manage your UV exposure right on your wrist.

Sola optionally integrates with Apple Health app, specifically to read your Fitzpatrick Skin Type and to keep track of UV index that you were exposed to.

Also included now is Vitamin D tracking.

Lastly, thanks to its monochrome themes, you can actually interact with the app in bright sunlight, especially if you are wearing sunglasses.

All access can be unlocked with either (1) an annual subscription, or (2) a one-time purchase valid for lifetime.


Sola is designed to provide helpful information, to the best of the developer's knowledge and scientific research, about the extent of exposure to solar UV radiation considering various factors such as skin type, existing tan, location, UV light intensity, applied sunscreen, and so on.

However, such information is not meant to be used, nor should it be used, as replacement for common sense, independent mature judgement, or healthcare advice.

To the maximum extent allowed by law, the developer shall not be held responsible or liable for any damage or consequences from any action by any person in connection to using or inability to use this app.

I’ve been using this app not for tanning but for my newborn and sun/UV exposure. It’s been fantastic. I had a few “hick-ups” at first but the app support was amazing and worked helping me figure everything out!!! I 100% suggest using this app!!

2023 - still using and is still awesome!!

Very Helpful!

Sooo much better than just using the UV rating from weather app! This app helps me plan an exposure and prevent burns. I usually fry myself early in the season - and this year I haven’t! I appreciate the science behind the calculations. Based on my experience they seem to be right on.
