Grip & Shoot
Are your smartphone videos too shaky to show? Grip & Shoot can solve that. The product is made up of a hand grip, an iPhone case (it comes with two: one for an iPhone 5/5S and another for a 4S), and an app that pairs the handle and case with your phone via Bluetooth 4.0.
Once paired, you can use the Grip handle to control your smartphone camera. A trigger lets you take still pictures or videos; two +/- buttons let you zoom in or out. You can also detach the Grip and it will still take pictures from up to 100 feet away from your phone.
Although Grip & Shoot does not currently work with Android-based phones, the company is working on it.
