A Prime spiral or Ulam spiral is a cool visualization of prime numbers that spiral out from a starting number. This app allows you to dynamically control the number spiral using tapping and sliding motions.
You can control the starting number in several ways. Single tapping on the screen will either increase or decrease the starting number by one. You can also move your finger in circular motions on the screen to either increase or decrease the starting number.
From the toolbar menu option you can quickly adjust the starting number as well as change the circle size. Note: super small circle sizes require more calculations so expect the app to run slower.
