An extension for MIT App Inventor 2.
MathFlowers lets you create beautiful mathematical flower patterns on a canvas.
Set numerator and denominator values to create different patterns,
customize colors, line thickness, and special effects like oil paint or dashed lines. Animate your flowers with adjustable speed and rotation.
or generate random flowers. You can also control the animation speed, pause/resume drawing, and rotate the flower.
You can also save the flower as a PNG or JPEG image file.
