Previously, for measurement, we have tried to use AR technology which relies on 3D vector's position / nodes using distance formula as follows: let distance = sqrt( 						pow(end.position.x - start.position.x, 2) + 								pow(end.position.y - start.position.y, 2) + 								pow(end.position.z - start.position.z, 2) 				) We wanted to know is it possible to use CoreMotion instead for measurement? Where we thought of moving our phone from point A to point B to measure the distance (less than 100cm) between these 2 points in metrics (m or cm) from it. If not using CoreMotion or Measurement with AR, then is there any suggestion on what should I use in iOS? Thank you
