Blinq is a line of fashion-forward jewelry that lets you keep your smartphone tucked away in a purse or pocket, yet still be (discretely) notified when a call, text or email comes in, as well as other notifications tied to your calendar or favorite apps.

Available now, the Motiv Ring is a fitness-centric wearable.

At less than 0.1 inches thick, the titanium Motiv Ring is thinner than two nickels and weighs less than a penny.

Available in white or black, NFC Ring comes with two special NFC tag inlays inside the ring, one for public information and one for more sensitive stuff, says the company.
