This creates a template for iOS app prototypes. The aspect ratio of iPhone 5 and 6 series phones is 16:9. Since the Scratch workspace is 480 x 360, we will use its full height, or 360 points. We need to find the correct width, which should be 9/16*360, or 202.5 points. That means that the iOS screen should have dimensions proportional to 202.5x360. This program draws two vertical lines, each 101 points away from the origin, for a total of 202 points. You can remix this template in order to see what your iOS screen will look like.
