Officially called the “Click to Pray eRosary”, this just might be the strangest smart gadget you’ll ever come across. It’s shaped like your standard rosary and designed to teach the technology-focused youth how to pray properly. The eRosary can be worn like a bracelet and is activated by making the sign of the cross. There’s a companion smartphone app which synchronizes with the gadget and gives you access to an audio guide, exclusive images, personalized content, as well as to track user progress.
