Frequently asked questions

Where does Suncap get the UV data?

After asking for your permission, Suncap utilizes your GPS location to anonymously obtain weather and UV index-related data from Dark Sky, one of the most accurate sources of hyperlocal weather information. The data is refreshed every time you open the app.

Is Suncap free?

Yes, and it will always be. We don't plan on adding any in-app purchases or subscriptions. We are also not in the business of selling your data to third parties or using your data to target ads at you.

What features do you plan to add in the future?

We plan on giving you the ability to specify your location manually and to enter multiple places at once. We also plan on adding a home screen widget and integrating the UV data with the IOS health app.

Why am I asked to provide my Skin Type?

Suncap collects your skin type to estimate the maximum amount of time that you can spend outside before seeking shade. It follows the Fitzpatrick skin typing, a scientific skin type classification. Each skin type has a different coefficient that affects the maximum exposure time recommendation.

Your feedback matters

Hi, I'm Julien, the developer behind Suncap. I build this app in my spare time to help people who, like me, need to limit their exposure to UV rays.

Overexposure to UV radiation is a serious public health issue. In the US alone, more than 3 million people are diagnosed with skin cancer each year, and the numbers are growing sharply year-over-year.

This app is a modest attempt to help with the prevention effort. It aims to be intuitive, informative, and free. If you have suggestions to make it better, feel free to reach out.

if you find it useful, please consider rating Suncap on the App Store .
