How many times have you attempted to use your smartphone to take a group shot but could not quite reach the button to snap the photo? Now you can just tell your phone to snap away. For Android, an app like Camera ZOOM FX ($3) has voice-activation. VoiceSnap for iOS ($1) does the same thing for iPhones and iPads. These apps are perfect for taking photos from a distance when there is no one around to take the picture for you.
