Accumulated UV exposure from the sun is the most significant cause of wrinkles, premature ageing and even skin cancer. Also, not receiving enough sun reduces your Vitamin D levels and can contribute to seasonal depression. Now, your existing phone or AndroidWear watch can effortlessly monitor your exposure, and alert you when the sun (or lack of) threatens your health.

Track your solar ultraviolet exposure on the ski slopes, at the beach, or on the go. Decades of scientific research and groundbreaking physical models now allow your phone's internal light sensor to accurately measure your ultraviolet exposure from the sun!

*NOTE: Most phones have a limited internal light sensor that can't detect bright light. This is not a bug in the app, but a limitation of the phone hardware. However, performance is very good with the Sony SW3 and some recent, high-end phones.

-Compatible with some Android phones and the Sony SmartWatch 3

-Track your exposure on an Android phone or on the web

-Alerts you when you've reached the limit

-Reminds you to go outside if you haven't had enough sun

来自太阳的累积UV曝光是皱纹，过早老化，甚至皮肤癌的最显著原因。此外，没有得到足够的阳光减少你的维生素D水平，并有助于季节性抑郁症。现在，您现有的手机或手表AndroidWear可以毫不费力地监控你的曝光，并提醒您，当太阳（或缺乏）威胁到你的健康。

轨道上的滑雪场的太阳紫外线照射，在沙滩上，或在旅途中。几十年的科研和开创性的物理模型现在允许您手机的内部光传感器准确地衡量你的紫外线照射的太阳！

*注意：大多数手机都有一个有限的内部光传感器无法检测到明亮的光线。这不是在应用程序中的错误，但手机硬件的限制。但是，性能非常不错的索尼SW3和最近的一些高端手机。
