Sola is a lifestyle app designed to help you make the most of the sun while staying safe. It calculates and tracks your sun exposure based on the current UV index forecast, your skin type, existing tan, sunscreen SPF, and sunbathing habits. With a convenient Timer feature, Sola reminds you to reapply sunscreen, flip over if needed, and take breaks from the sun.

The app also includes an Apple Watch extension, allowing you to manage your UV exposure right from your wrist. Sola can optionally integrate with the Apple Health app to read your Fitzpatrick Skin Type and track the UV index you were exposed to.

In addition, Sola now offers Vitamin D tracking, helping you monitor your vitamin D levels. The app's monochrome themes make it easy to use even in bright sunlight, especially when wearing sunglasses.

Please note that while Sola provides helpful information based on scientific research, it is not a replacement for common sense or healthcare advice. The developer is not liable for any consequences arising from the use of this app.
