About
Geometrica is a geometry-based drawing app crafted for tattoo artists but embraced by creative professionals across many disciplines. Developed by second-generation tattooer and geometric/dotwork pioneer Cory Ferguson, it brings 30 years of industry expertise into a powerful, intuitive digital canvas available on iPhone, iPad, and Mac. At its core, Geometrica excels in symmetry and pattern-making. The Rotation Effect (mandala maker) supports up to 200 mirrored segments—far beyond competing apps. The Repeat Effect tiles drawings into horizontal or vertical band patterns; Polar Repeat creates concentric circular rows with optional spiral drawing; and the Wallpaper Effect unlocks all known symmetry groups with deep customization. Gradient Thickness adds dynamic line variation across dozens of configurable directions, combinable with any symmetry tool. Drawing tools are equally impressive: the Marker Tool features tapers, whip shading, and a rope stabilizer for smooth curves; the Straight Line Tool snaps to grid points for precise industrial-style work; and the Dotwork Tool offers fully customizable pointillism with variable dot size, density, and randomization. For professional tattooers, Geometrica includes folder-organized galleries, a one-click Convert to Lines function, adjustable grids (square, hexagon, isometric), layer rotation in 5-degree increments, and an advanced print system that automatically tiles any design to any physical size—eliminating the need for photocopier resizing when creating large stencils. Monthly pattern packs provide ongoing creative inspiration. Whether you are a tattoo artist perfecting a geometric sleeve, an illustrator designing mandalas, or a quilter planning intricate block layouts, Geometrica delivers an unparalleled creative toolkit.
Key Features
- Advanced Symmetry Engine: Rotation (mandala) effect with up to 200 mirrored segments, Repeat, Polar Repeat with optional spirals, and fully customizable Wallpaper symmetry groups—all usable simultaneously.
- Gradient Thickness: Lines dynamically increase from thin to thick across the canvas in multiple directions with dozens of configurations, combinable with any symmetry effect for breathtaking results.
- Professional Drawing Tools: Marker tool with tapers and rope stabilizer for smooth curves, snap-to-grid straight line tool for precise industrial designs, and a highly customizable dotwork pointillism tool.
- Print at Any Physical Size: Enter exact real-world dimensions and Geometrica automatically tiles the artwork across as many pages as needed—perfect for producing large tattoo stencils without a photocopier.
- Monthly Pattern Packs: Subscribers receive 6 new curated patterns each month showcasing the full creative potential of Geometrica's symmetry and drawing toolset.
Use Cases
- Tattoo artists designing geometric sleeves, mandalas, and dotwork pieces with precise symmetry and print-ready stencil output
- Illustrators creating repeating tile patterns, decorative wallpaper designs, and mandala artwork for print or digital use
- Quilters planning intricate geometric block layouts using symmetry tools to visualize repeating fabric patterns
- Graphic designers generating complex radial and band-pattern assets for branding, packaging, or editorial illustration
- Art students and hobbyists exploring symmetry groups, geometric construction, and pointillism techniques in an intuitive app
Pros
- Purpose-Built for Tattoo Workflows: The only drawing app created by a working tattooer for tattooers, addressing niche needs like large-format stencil printing, dotwork shading, and gallery organization.
- Unmatched Symmetry Depth: Supports up to 200-segment mandalas, concentric polar repeats, spiral drawing modes, and all known wallpaper symmetry groups—far exceeding typical drawing apps.
- Broad Creative Appeal: While tailored for tattoo artists, quilters, illustrators, and pattern designers all find it equally powerful for their symmetry-driven creative workflows.
Cons
- Apple Ecosystem Only: Available exclusively on iPhone, iPad, and Mac—no Android, Windows, or web version exists, limiting accessibility for non-Apple users.
- Niche Orientation: The specialized focus on tattoo-artist workflows means some general graphic design features common in broader apps are absent or underdeveloped.
Frequently Asked Questions
Who is Geometrica designed for?
Geometrica was built primarily for tattoo artists working with geometric and dotwork styles, but it has grown popular among illustrators, quilters, and any artist who works extensively with symmetry and repeating patterns.
What symmetry tools does Geometrica include?
Geometrica includes a Rotation Effect (mandala maker with up to 200 mirrored segments), Repeat Effect (horizontal or vertical band tiling), Polar Repeat (concentric circular rows with optional spiral modes), Wallpaper Effect (all known symmetry groups with customization), and Gradient Thickness—all of which can be combined simultaneously.
Can I print designs at a custom physical size?
Yes. Geometrica's print system lets you specify exact physical dimensions—such as 28 inches tall—and automatically splits the artwork across as many pages as needed, so you can create large stencils without relying on a photocopier.
Is Geometrica free to use?
Geometrica is free to download from the App Store with in-app purchases available for premium features and monthly pattern pack subscriptions.
Which devices does Geometrica support?
Geometrica is available on iPhone, iPad, Mac, Apple Vision Pro, Apple Watch, and Apple TV through the Apple App Store. It is not currently available on Android or Windows platforms.
