Sun Protection You Can't Ignore
Smart UV-tracking wristwear that physically retracts into waterproof housing when you're not sun-exposed, then extends with haptic feedback and a wasabi-scented micro-burst alert when it's time to reapply sunscreen.
Real-time UV monitoring knows your exact exposure better than you do.
Yoyo-style waterproof housing protects the device when not in use.
Haptic feedback + scent burst creates an unmistakable alert.
You're tubing down a river, feet in the water, having forgotten about sunscreen. Suddenly your Rayyo extends with a vibration pulse and releases a tiny burst of wasabi scent so distinct and alert-triggering that you instantly pull over to reapply—your skin saved because the system knew your exact UV exposure better than you did.
