Apple Watch Series 4 will let you know if you need to apply sun screen before going out

Apple Watch Series 4 will let you know if you need to apply sun screen before going out
Yesterday, we showed you a leaked image of the Series 4 Apple Watch that will reportedly be unveiled by Apple on September 12th. The larger edge-to-edge display has room for eight complications, including a new one seen in the lower left corner of the render. What appears to be a UV Index reading is seen, including a scale. The scale appears to be in line with the ones used by the WHO and the EPA.

With the UV Index reading available, those with the Series 4 Apple Watch will be able to know in advance, with a glance at their timepiece, whether they need to slather on a ton of sun screen before going outside. A reading in the 6 to 7 range indicates that unprotected skin will be at risk outdoors. At that level, the EPA suggests applying SPF 30+ sunscreen every 2 hours, even on cloudy days, and after swimming or sweating. A higher reading calls for minimal exposure to the sun from 10am to 4pm, and the donning of a hat and sunglasses.

This new feature is all part of Apple's health initiative, one that heavily depends on data compiled by the sensors on the Apple Watch. The device has already shown itself to be capable of saving lives by monitoring a wearer's heart rate. With an easily accessible UVI reading, the timepiece can help prevent severe sunburns, skin cancer and other serious health issues from affecting those who heed its warnings.

That's called INNOVATION!! Now we'll wait and see how all the other followers will follow this BRAND NEW feature in the coming months.

Innovation? There are dozens of apps that show this information on your smartphone and smartwatch for more than a year now. Including ones that incorporate it into a watch face. But hey it's nice to see they were Apple innovating

Get lost you Apple hating troll. Who talked about a silly App? The fact that Apple did implement this feature in to their original hardware + software is itself an innovative thing.

sorry, can you please tell me which sensors are handling the uv reading? this is really interesting if is really more than just software. From the article is not clear, looks like you already know exactly how is working. Other than that, yeah are many apps doing the reading via meteo stations in the world.

Haha ahhh someone is butt-hurt. So taking features from apps is now considered innovative. Besides it's not even sure if they implemented a UV sensor into the watch or just get the info from a weather source. Also, a UV sensor has already been done by the Acer Leap Ware smartwatch back in May 2017.

Actually Gear S released August 14 2014 had a UV sensor.

On a sunny day with temps above 75 degrees, you're not smart enough to wear sunscreen? Haha. I guess you need to be told when to shop, do chore and play with the kids too? By the way, the Gear S3 already had this feature since day one

"Get lost you Apple hating troll"....isn't that a little bold, coming from the resident Anti-Samsung troll?

You dummy. Apple implementing something already done, be it app or not, is not innovation...that’s implementation LMAOOOOO.

Maybe you should’ve edited that post, before those 240 seconds were up lol. Your ass is getting grilled.

Perhaps sunscreen will help against the burn?

It sure is and the Microsoft Band 2 had a UV sensor on it two years ago, the Samsung Gear S even before that...Thanks everyone else for giving Apple the idea and that is to Apple for finally joining the party.

I mean if Samsung could do the UV reading. With an "actual sensor " on the Gear S I'm sure apple can too. Lol

Hmmm. Sun's up without all-day heavy overcast? Sunscreen needed. No app or watch necessary - ever.

Wrong broseph. You still need sunscreen during those cloud days. Clouds doesn't block that much UV rays.

Actually it does if it's enough clouds.

Apply sunscreen, how stupid can you get, like nobody can look outside and see what the weather's doing. Looks like it only reads UVB too, since there aren't EPA ratings for UVA.

9. peace247 unregistered sure knows how to hype up useless features.

I think the article is just informing us that finally, Apple is now catching up and including this feature. It's good for the customers.
