Pikunoki vs Divisors

Pikunoki is a pixel art creation app for iPhone and iPad. With simple, intuitive controls, you can draw pixel art, work with layers, and create animations. Pikunoki also supports Apple Pencil, making it especially comfortable to use on iPad. The app includes useful tools for pixel art creation, such as a pen, eraser, fill tool, move tool, rectangular selection tool, and eyedropper. Choose colors, stack layers, move parts of your artwork, and build detailed pixel illustrations one dot at a time. Pikunoki also supports frame-by-frame animation. You can add, duplicate, reorder, and delete frames, preview your animation, use onion skinning, adjust the frame duration, and export your animation as a GIF. You can import photos and images as new pixel art layers, and share your finished artwork as a PNG image.

This app can tell you if a number between 0 and 20000 is prime or not. It can also determine all divisors of any number less than 10000000. Fancy a game? Then you can try the quiz and collect points. Siri Shortcuts are also supported: You can also use your shortcuts to check whether your number is a prime number or not. Another shortcut can give you all the prime numbers from 0 to your entered number in a list. A shortcut can be used to determine all divisors of any number less than 100000, so the shortcut doesn't take too long.
