9 Stack AR
Admittedly, Stack AR is not the flashiest or most comprehensive augmented reality app. Really, the only thing it does is allow users to place and stack blocks using AR. But its simplicity is its main strength, as it happens to be one of the best ways to show off ARKit’s capabilities to your non-tech savvy friends and family. Just hand them your phone or tablet and watch the resulting amazement. Stack AR is free to download and use. Get it here.
