Check out the Pictar Smartphone Camera Grip (Plus), a device I would have linked to in a Cool Stuff Found article if we didn’t have a deal for it. It’s a camera grip that fits most iPhones, and it does that in a very clever way. Rather than matching physical buttons or even using a wireless connection for camera controls, this device emits high frequency sounds you can’t hear, but that the free companion app can. That allows you to control all manner of camera settings on your iPhone while using very little power. And you can 15% on the Pictar Smartphone Camera Grip (Plus) through us and get it for $92.99.
