There’s some lighthearted tone, friendly science talk, and occasional humor to keep things lively, but the science is legit. If any joke hits a nerve, please know none was meant to offend.

Remember sun protection in autumn

In late summer and autumn, when the sky is cloudy, many people neglect to protect their skin from the sun’s rays – a widespread misconception that not only has unpleasant consequences, but also significantly increases the risk of skin diseases.

Clouds act like an invisible veil that seems to block out the sun. In reality, however, clouds allow up to 80 percent of UV rays to pass through. So-called “light” clouds are particularly dangerous, as they can reflect and even intensify sunlight. The deceptive thing about a cloudy sky is that you perceive the sun as less intense and therefore underestimate the risk of sunburn. The result: you stay outdoors longer without adequate protection – and your skin pays the price.

To minimize the risk of sunburn even on cloudy days, experts recommend always applying sunscreen with a high sun protection factor (SPF 30 or higher), especially if you are spending a long time outdoors. Sunscreen should be applied generously and reapplied regularly, especially after swimming or heavy sweating. Additional protective clothing such as sun hats, sunglasses, and light clothing are also advisable.

So anyone who thinks that sunscreen is unnecessary on a cloudy day should think again. Even in the shade or when the sky is slightly overcast, the danger is real and probably worse than you might think. The rule “better too much than too little” applies especially to sun protection. Your skin will thank you for it!

Great quality, fast turnaround, and a pleasure to work with.

Ongoing issue with Apple Weather for some users

It seems there’s an ongoing issue affecting weather forecast retrieval for some users. An increasing number of developers have reported similar problems (cases: 789157789900789564, 789319, 786126, 788811 . I’ve already reported this to Apple and will share any updates here as they come. In the meantime, I’m working on a workaround. Apologies for the inconvenience to anyone affected.

UPDATE: Apple just reported that the issue should be resolved. Please reach out at support@getsola.com if you continue to see “clear-skies” UV forecast instead of from Apple Weather.

Sola – Sun UV & Vitamin D Timer

Sunlight enhances your mood, relieves stress, improves sleep, and triggers vitamin D production. But too much sun exposure increases your chances of sunburns and skin cancer.

Sola calculates and tracks how much sun exposure you are getting based on current UV index forecast, your skin type, any existing tan, sunscreen SPF, and more.

Sola features a convenient Timer that reminds you when to re-apply sunscreen, when you need to get out of the sun, etc.

It also comes with an Apple Watch extension so that you can manage your UV exposure right on your wrist.

Sola optionally integrates with Apple Health app, specifically to read your Fitzpatrick Skin Type and to keep track of UV index that you were exposed to.

Also included now is Vitamin D tracking.

Lastly, thanks to its monochrome themes, you can actually interact with the app in bright sunlight, especially if you are wearing sunglasses.

First FREE week issues

There was an issue with annual subscriptions not offering a first week free. That is now fixed. Apologies for users who were charged right away – if you were, feel free to reach out to me and we can sort it out.

New updates to Sola

It has been a long while since the last update – sorry for the long silence. I have added Widgets so that users can now get timely information from Sola at a glance on their Home Screen, Lock Screen, or Today View.

I have also added the Italian version. The Portuguese is in the works and should become available soon.

In addition, the Apple Watch experience has been improved as well, with the new UV index chart and the addition of Vitamin D information, to mirror the iPhone app.

Finally, after a long pause, I am re-starting the development of the Android version of the app. So stay tuned 🙂
