QSun is a sun safety wearable device and companion app that tracks your sun exposure to help you prevent skin damage while maintaining healthy vitamin D levels. It notifies you when you’re about to get sunburned so that you can keep doing what you love under the sun. As an advanced AI-powered wearable, the QSun device monitors and analyzes your sun exposure in real-time. The algorithm combines your current sun exposure with your skin type, environmental situation and sun safety habits to give you tailored recommendations.
