This is the second time I've tried multiplayer phone and tablet AR this year: The first was at Google's developer conference just weeks ago, using an iPhone and Google Pixel. Google calls its cross-platform cloud-based AR tech Cloud Anchors (one app already uses it).

Apple's multiplayer AR, meanwhile, doesn't necessarily have to be cloud-based. But it's similarly surprising, and similarly captivating. Trying an AR experience out on your own is one thing, but sharing the experience with someone else lends it an extra dose of convincing immersion. Suddenly, augmented reality feels a lot more real.
