Raymio is a wristband that you wear when you’re outside. It monitors your sun exposure and sends you alerts, reminders, and tips to keep you protected. The band connects to an app on your mobile phone (iOS or Android), which keeps track of your exposure history. It also provides helpful sun protection tips for your skin type. Anyone in your family can wear it. The app will keep track of different users. So you can put it on your children and monitor his or her sun safety when you are not using the band. You don’t need to keep looking at your phone. When the band flashes red, you know it is an important alert that requires you to take action. If you want, the app will connect you with other family members and friends so that all of you can share information with each other.
