★★★★★ App location not updating and won't restore my lifetime pro purchase. Please fix

★★★★★ Loved this app initially — paid for a yearly subscription & now it doesn't work at all.
★★★★★ This is a useful app and I like the widgets, but I'm absolutely not going to pay some way overpriced subscription for something I can get for free, albeit slightly less conveniently.
★★★★★ Life is expensive and a uv app is just not a necessity!
8 of the 1 and 2 star reviews.
★★★★★ They recently did an update on it & it doesn't let you see the forecast for when the highest peak of UV is.
★★★★★ The location doesn't seem to update well either - I'd be hours in a different town, and it would still show the previous one.
★★★★★ Update: 22.07.2020 Der Entwickler hat sich bei mit gemeldet und meinte das alles besser werden sollte nachdem update was heute rauskommt.

★★★★★ The phone app won't stay open & the app on my watch reads 0.0 24/7…. Loved this app initially — paid for a yearly subscription & now it doesn't work at all. 😩
★★★★★ Heads up the app isn't opening. With new Apple update
★★★★★ Version 5.1.2 is crashing on launch on my iPhone SE running IOS 12.3.

★★★★★ App location not updating and won't restore my lifetime pro purchase.

★★★★★ My skin is very fair and I have to check it with Dermatologist as well but this app helps me to be on track👍🏻 Is excellent
★★★★★ I spend a lot of time outdoors, it's very helpful to know when I need to reapply my sunscreen or when I'm at risk to burn.
★★★★★ I want to get tan before I go to the beach and this helps me do just that 5 stars

★★★★★ Simple and easy to see when the sun is strong enough for me to tan effectively.
★★★★★ Have been using this app for years. Gives great visuals. Love to track my UV exposure, and it integrates seamlessly with Apple Health. *One update I'd like to see is the addition of higher sunscreen SPFs. Current…
★★★★★ It's simple and easy to use.

★★★★★ Anywhere I go I can see how the UV Index is what's the number. My skin is very fair and I have to check it with Dermatologist as well but this app helps me to be on track👍🏻 Is excellent
★★★★★ but… - IV widget isn't accurate recently.
★★★★★ and tbh I feel like it shows you more detail than apple weather app and it's also pretty accurate I think!
11 of the 4 and 5 star reviews.
★★★★★ I also love the widget which is also free.
★★★★★ I bought the lifetime subscription and it's worth every penny.
★★★★★ I have the widget on my watch, my iPhone and could not be happier with the free version.
8 of the 4 and 5 star reviews.
★★★★★ Design could be better and it would be great if it would automatically grab the time in daylight value from HealthKit instead of having to manually activate sun exposure in the app.
★★★★★ having full awareness of the UV index being able to fully protect your skin while enjoy the beautiful benefits of sun and the UV index is below… Is unmatched.
★★★★★ Perfect App :-) Good Design, good Data

Simple and easy to see when the sun is strong enough for me to tan effectively.
Anywhere I go I can see how the UV Index is what’s the number. My skin is very fair and I have to check it with Dermatologist as well but this app helps me to be on track👍🏻 Is excellent
One of my favourite apps Works fantastic! ✅✅✅✅✅
Best such app I’ve found. but… - IV widget isn’t accurate recently. It just now showed a UV higher than the daily peak shown in-app. 🤔 - i wish it would notify at multiple UV levels instead of just one. - a “go get some Vitamin D” notification would be nice when i haven’t met my goal by X hours before sunset.
Made my life easier, healthier and more comfortable.
Great for tanning I got a great tan this summer
