JUNE is a sun protection coaching bracelet. It is the first bracelet that measures sun exposure. It is connected to a companion App in the user’s smartphone, which advises women how to protect their skin on a daily basis from the effects of the sun. JUNE and its companion App offer a new serenity in the sun. June tracks UV intensity in real-time and the total sun exposure absorbed by the user’s skin throughout the day. Depending on the user’s skin type, time spent in the sun and UV Index intensity, the App in the user’s smartphone calculates the maximum daily exposure. Every woman can monitor their sun dose, measured in percentage, throughout the day. To avoid sun damage, the App notifies the user when and how to protect their skin, giving precise Sun Protection Factor sunscreen recommendation. The App also features a summary of time spent in the sun, allowing the user to see when the UV rays impact on the skin was most intense during the day.
