An iPhone and iPad app for making geometric patterns easily with your fingertips — design print-ready material, or simply enjoy watching the patterns unfold.

On the App Store (English), the app is listed as Fineline Studios.

What it does

• All 17 wallpaper groups — every way a pattern can repeat in the plane, from simple translation to sixfold kaleidoscopes.
• Seamless by construction — the repeat unit tiles the plane without seams, and that unit is what you export.
• Print-ready export — SVG and PDF vectors, or images at an actual size in cm with a chosen DPI.
• Draw by hand — sketch inside one cell and watch the symmetry replicate it across the plane.
• 105 curated palettes — including traditional Japanese colours, plus automatic colorways of your current pattern.
