IKEA's augmented reality Place app can be helpful for gauging how furniture will look in your abode, but you've been limited to trying items one at a time -- not much help if you're trying to furnish a new home. Now, though, it's much more practical as a home decor tool. An updated iOS app (the Android equivalent is coming in the "near future") lets you place multiple items at once, whether they're handpicked or part of pre-defined Room Sets. You'll know if that lounge chair and lamp combo fits in with your living room, for instance.
