Violet is the first wearable device that provides customized user guidance on optimal sun exposure, and also checks that you’re getting enough sun.
In sync with a mobile phone app (iOS and Android) Violet monitors real-time UV exposure, alerts you before the measured UV dosage approaches a limit, and calculates your daily natural vitamin D production. By measuring both detrimental and beneficial effects of UV light, Violet aims to help users achieve optimal sun balance.
Violet will include two accessories: a clip and a wristband. See also: Best activity trackers.
The company has developed proprietary algorithms to measure UV dose and vitamin D production, taking into account various personal factors.
Scientific evidence has shown that vitamin D is vital for good overall health. Many studies have linked vitamin D deficiency to numerous diseases, including cancers. Your body makes its own vitamin D when you expose your skin to sunlight.
But we also all know that too much sun exposure can also lead to life-threatening diseases such as skin cancer.
Violet is designed as a solution to encourage behavioral change toward better health by minimizing the risks while maximizing the benefits of sunlight exposure.
Development continues on features such as expert guide/forecast on optimal sun exposure, crowdsourcing of measured data for maximum accuracy, and a dynamic SPF model taking into account sunscreen wearing off.
The prototype design of Violet is complete, with device firmware and mobile app functional.
Violet has a Kickstarter goal of $100,000 in order to begin manufacturing and making Violet available in spring 2015.
