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.

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.

I genuinely think, at full working capacity, this app would be my godsend. I love the idea of an hourly forecast and push notifications for a customizable UV Index. And as a UX designer, it’s my opinion that this UI looks clean and intuitive, which I highly appreciate.However, the app doesn’t seem to recognize that I started my 3 day trial. The app store shows I’m subscribed, but the app is still blocking me from accessing premium options. I’d love to try out this app and base my rating off of my actual experience with it after this is resolved.Edit: It actually seems to be very inaccurate. The app said it was UV 6 when it was actually UV 8. That’s a large disparity. I think I’ll stick to the default weather app on my phone, unfortunately.

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 love this app, and use it to help know when I need to be more careful with my time in the sun.However, I’m noticing large periods where it doesn’t work. It isn’t showing the UVI, I’m not getting the alerts I requested for the UVI going above or below the requested alert level, and it’s incredibly infuriating. I work outdoors, and I have a housemate who’s sensitive to the UVI, and we both rely on those alerts as well as the app actually telling us what the UVI is. Right now, as I type this, it’s saying the UVI is 0 with a peak UVI of 0, bug when I go to the forecast it says the peak is 6. This needs to be fixed.

I use this app everyday to track how intense the sun is going to be today. I wish there was a way for it to track the cumulative amount of sun that you receive much like the movement tracking on the Apple Fitness app. Then when the sun is down, add that data to the health app. It needs more options for clothing coverage such as a hat, combo for shorts and long sleeve shirts. Overall it’s a great version 1.4 but a version 1.9 with these options would be just fantastic.

The bug 🐞 is when traveling the Apple Watch app doesn’t update with your location. The annoying fix that I have used was to close the app on the watch and restart the watch. Sadly it sometimes takes multiple attempts to fix this. Developers, please fix this bug. Overall it is nice to quickly see the UV high for the day and decibel granularity. However, the zero isn’t needed on the complication, it just takes up space.

The app is good… I especially like the ability to track sun exposure. The one thing that keeps this from being a 5-star app (and the reason I use a different app) is that the widget offerings are a little lacking. These only show the UV index number, or only show how much time you have left in the sun for the day. Other UV app widgets show the current weather, amount of time before burn and how long to get the Vitamin D needed, in addition to the UV index, in one small widget.

From what I can tell there is no way for this app to update the apple health UV index data if you kill the app. While this is understandable, this was only mentioned *after* they force you to pay for the feature. That felt annoying. If that was fixed I would update my review.UPDATE: Developer response was good and they considered my suggestion. Updating to 5 stars. Thank you.
