Epicycle Gallery

Explore original mathematical sketches, then see each curve rebuilt as a chain of rotating circles. Fourier Lab, Circle Composer, Freehand Fourier, and Paste Diagram let you experiment with harmonics and create your own patterns.

When you paste a line image, Apple’s Vision framework extracts its contour on your device. The App Store has the current compatibility, screenshots, and release information.

Epicycle Gallery’s App Store privacy disclosure says data is not collected. Drawings, pasted text, and pasted images are processed on the device and are not uploaded. The app reads the clipboard only when you choose a paste action; it does not monitor the clipboard in the background.

See the collection privacy policy for general information.
