Tom’s Guide:

There are two kinds of people: those who have needed tech support, and those who constantly give it over the phone to their friends and families. Both know how tricky and complicated this process can be, but Chalk — a new AR app launching today on iOS (for free) — looks to save the day.

Built by Vuforia, the company behind the tools used by the majority of augmented-reality apps, Chalk operates much like a videoconferencing call, connecting the cameras between two remote smartphones. (It’s iOS-only to start.) The only difference is that both use the rear-facing camera, so the person getting help can show the device or software they’re confused by, and the other person can draw on it.

This is one of those apps that really show off the upside of AR. I would have loved to have something like this when I did tech support.
