I love data, and I sunburn in 15 minutes, so it's no surprise that I've tried just about every UV index app in the app store. I've been a little unsatisfied with all of them until now; either they don't have features I want, or the API they're using stops working and the dev never fixes the app. This app is thoughtfully designed and a pleasure to use. After emailing the dev, Bjørn, to ask about adding a feature, I feel even happier about supporting his work. He was very friendly and replied within a day to let me know the feature already existed in the app and how to use it.For those curious: I asked about a feature to notify me when the UV index drops below a certain level, and Bjørn told me that whatever threshold I set for a "too high" notification, the app will tell me when the UVI goes above *or* below that. I just got a notification that the UVI dropped below 4, which means it's almost time for my walk, no sunscreen needed for me. :)If you're looking for cleanly presented, detailed data on the forecasted UV index and time to burn for your location, skin type, environment (pavement, snow, etc.), time of day, cloud cover, and more, this is your app. I paid for the pro features and would do it again in a heartbeat.

I’m very pale and burn easily. I work outside in the ecology field. 99% or my work day is spent outside and I need proper sun protection. This app is amazing for people like me who need to respect the sun. My only complaint is the function where the app warns you once a specified UV rating has been reached. I currently set mine to 3. Every time I get the notification alert that it’s UV 3 I open the app to find out that it’s well above UV 3. This isn’t a big deal to most people but for a lot of us this can be a matter of getting burnt or not. Still though. Very happy customer. App looks and feels good to use. The amount of times I’ve been sun burnt has gone down a lot since finding this app. However i fell that success rate would be higher if the alert notification mentioned earlier was more accurate.

Lots of apps have the UV index buried in the app. Dark sky has this too, but hunting for it with 15 taps is a pain. This app brings one of the most useful pieces of weather data front and center so I can plan my day and track my exposure. In the summer this app is a lifeline to help me avoid burning, and help me to know that even though the sun may be “hot” it may not be in the UV exposure that is harmful. In the winter and shoulder months, this app helps me to plan the most pleasant times to be outside, as the sunshine is often more useful than raw temperature. Fully supports widgets, Apple Watch, AW complications and great info. Thank you!

I like this app so much and am happy to have paid for the widgets! It makes a big difference in estimating my exposures and remembering how important sunscreen is and when to reapply (I am very pale and have a big family history of melanoma.) You can now edit the exposure tracker time if you forget to turn it off when you stop the current session, which is great. It would be even better if you could also subtract time once you had closed out of that menu. I have one really odd problem, which is that the UV always seems to read at a time about 20 minutes ahead of when it actually is. For example, it’s 4:21 and if I click and drag the sun to 4:21pm UV is supposed to be 2. But the sun is sitting slightly ahead of that and the UV reads 1.7.
