    Useless for now

    • Written by Svitozar R from Calgary

    Great idea but poorly developed. I bought it to be able to see “big” picture of how much UV radiation am I receiving during the day. It shows me my daily percentage but it does NOt import this data to Health app, but what it does it imports daily UV index from the app. Why do i need sensor to import UV index that is taken from weather server? Developers please, change it! Make it to import my actual UV exposure into Health app! Thanks.

    I've only had the sensor a few days, it never scans at the first attempt; like the Postman it only knocks twice ! and it's readings vary in an unexpected way: I understan under heavy cloud there is a likelyhood that there will be no UV, but under whispy clouds ?. It also gives readings in percentages, one cloudless day 160% (I didn't know this was possible, and can only assume it's bad) and the next with a few clouds as mentioned previously 23% ?. It would be helpful if it gave more information regarding these readings. It would seem that the device is aimed a much younger more beauty conscious demographic than a 50+ year old man who has concerns regarding skin Cancer (due to a mis-spent youth), who would rather not have more lumps cut out of his back, so was hoping this device would assist in decision making - but alas not. One of the functions of this device is just to sell more product which I have come to the conclusion is the main aim of La Roche-Posay in producing this sensor. ...' Tis a pity

    Great BUT Falls Off!

    • Written by Paulette W from Berlin

    When I first got it, it didn't have good coverage where I was living (Cusco region of Peru). I enjoyed using it at first when there was coverage. I lost it on a flight, so am going to try another one using safety pins to secure it.

    Does not do live monitoring of UV usage. Has the wearable chip that basically will map your activity, but does not do it live, it has to be scanned back into phone, so no tracking live. Basically it takes that info or what you tell it about when you were outside and measures the UV based on the weather / uv reports. So.. you can do all that without the app :( It will give you some skin tips, but I suspect you could also do those on your own. It should have a better description of the product as there is no "sensor"reading UV.

    No real-time tracking, no exposure warning, lots of ads

    • Written by Armin K from Cupertino

    The sensor may be tracking UV exposure, but your phone with the companion app does not. Only when you scan the sensor (slow and cumbersome) does the app get an update of accumulated exposure. This takes some practice and a minute or two of concentration, not practical to do frequently while out for a run or ride.
    In practice this means there is no warning when you reach UV exposure limit. No reminder to seek shade. Only when you scan the sensor at the end of the day, can you check if that painful sensation on your skin may be sunburn.
    Most of the app is just another weather app. You can get all that without paying for hardware.
    Oh, and even though you pay for this product, it still spams the user with a constant stream of ads.

    innovative and useful device

    • Written by Trisha C from Apex

    Great item! First off I have had this item since Dec 2018. The AQI and other weather related data from the app is likely from a local weather station not directly from you. But the UV data is from YOUR device and YOUR location. The connector seems flimsy. It doesn't disconnect from the device so I just pin the connector to my clothing to secure it. I have lost it and luckily it fell inside my clothes. I have also washed and dried it successfully (since t was pinned to my clothing). It works just fine. The most important takeaway is that it monitors your exposure to UV. If you're sun sensitive or a cancer survivor this is ideal for tracking your exposure. Despite the wonky clip it can go on a shirt or a hat or a necklace or sunglasses or your sleeve or a baby blanket etc etc. Just use a safety pin if you're afraid of losing it. The TRENDS section is pretty cool and helps me keep track of good days/ bad days. The average is misleading since UV damage doesn't occur as an average but interesting to note. I also appreciate the pollen index and types of pollen. Again it's local info not site specific but valuable nonetheless. Also I have no trouble scanning through my case. It takes a second to find but still efficient.

    Innovative device

    • Written by John L from Wilmette

    This is an interesting device. I like that it's so small that it can be worn unobtrusively in many locations on the body, although I wish it clipped onto stuff more securely since I'm concerned about losing it. I also like that it doesn't use any batteries so I don't ever have to remember to charge it. I know it is always working and ready to use. There is a history of skin cancer in my family so I am interested to see if this helps me track my UV exposure levels over time.

    My Skin Track

    • Written by James D from WALNUT CREEK

    I received as a gift and it is being returned. In my 30 years of dealing with Apple sold items, this is unquestionably a product that Apple should reconsider selling. First, the sensor attachment to the body is at best fragile; second the NFC is erratic or better put if commerce used it would be tossed; third a trial test gave aanswer incompatible with the strength of the sun and duration; finally the devise gave the wrong AQI for my location ( This is startling Given that it incorrectly connected to the internet).

    Not User Friendly

    • Written by Ana W from Austin

    I live in NYC and I really liked the idea of monitoring exposure levels. The first problem is the device is super small and hard to keep track of. Second, the little metal support is laughable. For the price point they should have done much better. Third, you have to take your phone out of the case every time you want to scan or sync. It’s very burdensome. Overall, great idea but poorly executed.

    Awesome new technology to track your UV exposure. As a person who has had sun poisoning multiple times, I am excited for help tracking my sun exposure and preventing potentially dangerous situations. The design is discreet yet stylish. Thrilled with this gadget.

    Tiny and simple to use

    • Written by Jonathan R from Plano

    From the construction (it's really small!), user friendliness (never needs to be charged), and useful, actionable data, this device is remarkable. I put this on my nephews shirt whenever we go to the park (he doesn't even notice it) and I'm able to track how much longer we can stay out before he gets burned (which my sister appreciates). Potential improvements: there should be an easy way to attach while swimming. Perhaps mounted in a rubber wristband so it won't fall off.

    Innovative Device

    • Written by Cassie L from Naperville

    The overall concept of the device is interesting and I can definitely see how it can be useful to understand how much sun exposure you're actually receiving. The hardware and sensor is very light and when you clip it on, you barely feel it. I think in the future, the sensor should come fully assembled. When I first received the product, it looked like it was ready to go; but then once you open the package, you have to take additional steps to set everything up. Other than that, great start so far!

    hardly noticeable when you wear it...cool device!

    • Written by Claire L from Naperville

    best thing about this device is that you cannot feel it at all when you're wearing it, which is super nice! maybe an improvement could be made to the initial setup of the device, as you have to attach the clip to the sensor yourself when you first open it and it was kind of hard to put on the clip. but otherwise, a cool device with a lot functionality that works well with your iPhone!

    Fantastic wearable device!!

    • Written by Yoonseok P from Evanston

    My 1 year old son is very sensitive to UV exposure so we need to check when should I put sunblock on him. I put it on his hat and t-shirt but he didn't care what is on his hat or t-shirt. I highly recommend this small and well-designed skin tracker to every parent.

    Revolution for monitoring skin exposure

    • Written by Tyler R from Goleta

    So far, this device has been very easy to use. The device itself is small, relatively unobtrusive, and can be clipped onto any place on the body. You can simply tap the phone (with the app open) next to the device and it automatically calculates your UV light exposure. While I've only had this for a day, it is easy enough to use that it will integrate seamlessly as a long-term part of my skin-care routine. It's really frustrating to do outdoor activities and not understand how much sun exposure I've actually received. I think that this will be invaluable to making sure I've put on enough sunscreen to prevent sunburns.

    One thing to note. The initial setup with the iPhone app was simple and very fast; however, I would have appreciated not having to give personal information to L'Oreal during the signup process. This is an issue separate from the actual operation of the device, but since the app is required for use it's something to be aware of if you are privacy conscious.
