The Netatmo June is the world's first sun-sensitivity wristband that measures the amount of sun exposure you receive during your day.

This smart wearable tech will analyze and suggest the safe amount of sun your skin can be exposed to, remind you of when to add sunscreen, and keeps track of your daily sun activity so you can protect your skin from harmful UV rays.

As with most smart devices this one is all about the app, it will give you an indication based on your skin type regarding sun doseage with and without sunscreen. When recommending you wear sunscreen it will suggest by SPF rating.

The jewel sensor itself detaches from the wristband and can be worn and a broach or attached to your headband or handbag.
