Fourier app for iPhone and iPad

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
