iOrnament: draw mandala & art

iOrnament is a state-of-the-art drawing tool that turns a single stroke into intricate mandalas and patterns using 17 crystallographic wallpaper groups. With Apple Pencil support, 3D Touch, rainbow colors, and a glow pen, anyone—from doodlers to professionals—can create fascinating ornaments. The app includes an interactive tutorial and a rich library of drawing tips, making complex symmetry approachable and fun.\n\nExport your work to Photos, email, or Facebook; work with transparent backgrounds; save, load, and recover sketches; and switch symmetry types on the fly. The 'design mode' blends several symmetries in one image, and you can preview fundamental cells, apply Escheresque color schemes, or add 3D ornaments and textures with in-app purchases. All of this is grounded in mathematical patterns, with a sampler of classical ornaments and a math-focused tutorial that teaches the theory behind wallpaper groups.
