This was a wonderfully exciting week to be an iPhone app. You know, assuming iPhone apps are sentient. But even if they aren't, at least they can fake it now thanks to GroupMe's adorable if not mildly bizarre emoji additions. And that's just the beginning! Dive in to see all the great iPhone apps we've rounded up for you this week.
GroupMe: GroupMe's a lifechanger. You should use it. This week it got emoji (good) that for some insane reason use its logo in place of a human head, and then attach things like beards and devil horns and headphones to it (uhh). The emoji update is just on iOS (iPhone and iPad), but will be on Android and Windows Phone 8 "soon". [Free]
eBay Exact: Chances are if you're normal and sane and at least remotely responsible with your money, you're not dropping £1,500 on a 3D printer. But that doesn't mean you can't tinker with 3D printing. eBay just released an app called Exact, that lets you customise and purchase your own items. [Free]
Groopic: The group shot dilemma—it's the bane of both narcissists and scrapbooking enthusiasts alike. But what are you supposed to do when you want to snap a pic of a precious moment between friends, but the only person around to take the picture is, well, you? Fortunately for you, Groopic has taken it upon itself to leave no group shot incomplete. [£1.49]
