Everything needed to build the artwork

Photo-based patterns

Position and zoom a portrait or subject inside a circular crop before generation.

Adjustable detail

Choose a preset or fine-tune pin count, thread moves, and line weight.

Simple workflow

Four steps from photo to physical art

The app handles the calculations so you can focus on choosing the image and building the final piece.

Thread Circle calculates the artwork on your device without uploading the photo.
