Almost all of us have defaulted to the smartphone for our camera needs, but it can be quite difficult to take group photos without buying some kit to work the timer properly. What you can do instead is use Camera Plus' AirSnap feature to pair two iOS devices, using one as a remote trigger while the other takes the picture. The image shows up in full screen on the triggering device, so you can always take the perfect anti-selfie – one that doesn't look like you're holding the phone at arm's length while straining your trout pout. Camera Plus is 89 cent for a limited time: a bargain solution to holiday snaps. http://iti.ms/1wROitQ
