Just kidding, it's not an invisible smartphone!
It's better: it's the Hot Watch, the first smartwatch that lets you make private calls.
The best part? You enable the private call functionality by cupping your hand to your ear. Kick-ass tech is what lets you--and only you--hear your incoming call. But to everyone else, it just looks like your smartphone is so future-style, it doesn't even exist in the corporeal world.
The Hot Watch has 35 days left in its Kickstarter campaign, and it's already $50k past its funding goal. Get in on the party by checking it out now.
