Geometrica for iOS

The first drawing app made for tattooers by a tattooer, full of innovative features and tools specific to working in the tattoo industry. We got straight to the point by eliminating features that are of no use to tattooers, and focusing on ones we need, many of which have never existed before. Version 1 of Geometrica is just the beginning, and as we grow, we want to include the wants and needs of the tattoo artist community. So please send us your feedback and suggestions, if there are features you would like to see in your drawing app please let us know. If we can put it in the app we will. Cory Ferguson can be found in person on the tattoo convention circuit and on Instagram.

SYMMETRY & PATTERN MAKING FEATURES

Stack and use these simultaneously!

MIRROR EFFECT

Replicates and flips your drawing across a guideline that can be configured horizontally or vertically, and offset using the offset feature.

REPEAT EFFECT

Replicates your pen stroke and repeats it in a row formation to create a band of pattern both vertically and horizontally. Combine with Mirror Effect to duplicate and flip as well as repeating in a row.

ROTATION EFFECT

Create mandala type designs up to 200 segments. Strokes can be mirrored or turn in the same direction.

WALLPAPER EFFECT

Create full page patterns. All 17 of the plane symmetry groups are here from P1 all the way to P6m. Customize the height and width dimensions for 8 of the 17 wallpapers.

GRADIENT THICKNESS

Gradually increase the size of your pen stroke from top of page to bottom, left to right or in a circular or square shape towards center. Use it simultaneously with any other Geometrica effects (eg. Wallpaper Effect) for a drawing experience you have to see to believe. There has never been anything like this before!

STRAIGHT & CIRCLE RULERS

Have an unlimited amount of rulers on the page and easily jump between them. Adjust angle of straight ruler in single degrees or snap to 15 degree increments to quickly access the most common degrees like 90, 45 etc.

DRAWING TOOLS

Weve kept the drawing tools simple to start in version 1 but of course we threw a couple innovative gems in there cuz thats just how we roll at Geometrica.

MARKER TOOL

Imitates the various sizes of marker a tattooer would typically use to create line drawings (back when we drew on paper like savages).

AIRBRUSH TOOL

For doing shading.

BUCKET FILL TOOL

Fill in areas with solid color, but ours works with symmetry effects, so if your pattern has 300 repetitions of the same shape, one touch of the bucket tool will fill all 300 shapes *mic drop*

DOTWORK TOOL

We realized early on that if we were going to release a Cory Ferguson drawing app, it had to have a dotwork brush, and then we took it to the next level. Adjust the size of the brush tip, the density of the dots filling that area and the size of the individual dots themselves!

STRAIGHT LINE TOOL

hold the Pencil on screen to draw perfectly straight lines that move and stretch until you decide theyre right where you want them and then lift the pencil. Works well with symmetry effects for sharp, industrial images and unexpected designs.

MONTHLY PATTERNS

Get new patterns every month which you can inspect, learn from and even use in your own drawings and tattoos.

SUBSCRIPTION

Because we rely on the support of the tattoo community, this app requires a subscription. After the 7 day free trial period ends, the cost of a subscription is approximately $10 USD per month. (Prices may vary depending on location)
