I have found tools like Smart Ruler that helps us measuring length using the screen. But for objects bigger than the screen I imagine there are apps that use the camera and focal length to show distances and widths. If there's no such app, is it possible to use a camera or any other common phone hardware to measure spatial dimensions?
