What's New

You can now import and squigglify SVG files, copy the Fourier equation coefficients (initial angle and radius), save pictures of your squiggles to your photo library, change the thickness and colour of the outline, use up to 500 epicycles to approximate outlines, and much more!

App Description

Draw a closed loop with your finger or Apple Pencil or upload a picture or of a silhouette or SVG file and I will transform it into a Fourier epicycle squiggle using the complex Fourier series!

Features:
• Import SVG files
• Import Images of silhouettes
• Copy the Fourier equation coefficients (initial angle and radius)
• Save pictures of your squiggles to your photo library
• Change the thickness and colour of the outline
• Use up to 500 epicycles to approximate outlines
