Interesting bit from the prompt in iOS 13. > "Walk around several feet and move your iPhone up and down until a balloon comes into view," Existing ultra wideband (eg Decawave) requires several "anchors" to triangulate the location of the tag. I wonder if Apple has built some way to locate the tag with its single anchor (the phone). Perhaps estimating the phones location as it moves up and down via accelerometer.
