Draw the Golden Spiral with the first few numbers in the Fibonacci series. See the Fibonacci formula.

Drawing the Golden Spiral: Touch anywhere on the screen to start drawing a Fibonacci square. The first square is drawn for you. When the last square is drawn, you will see the spiral beginning in red color. Touch within each square to see the Fibonacci spiral complete. Start the drawing over at any time by shaking your iPhone.

Copy a Fibonacci number to the clipboard (pasteboard) and paste it to another app or Notes later.
