"Apple says lidar will enhance the iPhone's camera by allowing more rapid focus, especially in low-light situations. And it may enable the creation of a new generation of sophisticated augmented reality apps."

My phone doesn't have lidar and hunts around for focus. Or focuses plain wrong. What's worse is that sometimes you take a picture (like of text) and it looks ok on the phone screen, but later when you check it's completely out of focus.

also there's distance measurement, and 3D shape/size estimation, but honestly I think fast/accurate focus will be the most awesome use case.

Maybe there could be some measurement-based applications? Automatic clothes measurements for Stitchfix? Automatic IPD measurement for Warby Parker?
