You already use your iPhone as a camera every day, so you might as well amp it up with a Snappgrip camera phone case.
Snappgrip is a camera controller that attaches to an included protective case. It adds a ton of useful features for when you're using your camera. It has tactile buttons for snapping photos, zooming in and out, and focusing. Using Snappgrip, you can also switch between orientations and switch the flash on and off. The case even has a tripod mount on the bottom. It really will make your phone feel like a classic camera and it looks cool.
The Snappgrip comes with a companion app and the team behind it is working to make it compatible with any camera app. It's charged through a micro USB port and the battery lasts up to 60 hours on standby.
