Geometry based drawing with innovative symmetry tools and features that cater to the workflow of tattoo artists. Sketching, line drawing, and complex patterns made easy.

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. 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 we can put it in the app we will.  Cory Ferguson and Geometrica can be found on Instagram. Tutorials are now on YouTube.

Stack and use these simultaneously!

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

Replicates your pen stroke and repeats it in a row formation to create a “band” of pattern either vertically or horizontally. Combine with “Mirror Effect” to duplicate and flip as well as repeating in a row. New for 2021 is a Polar repeat, which repeats your drawing in concentric circles that go from larger to smaller in the center. Plus use the curve slider to draw in a spiral!

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

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.

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. Customizable from 1 -10 rows of gradation. Use it simultaneously with any other Geometrica effects for a drawing experience you have to see to believe. There has never been anything like this before!

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.

We’ve kept the drawing tools simple to start but of course we threw a couple innovative gems in there cuz that’s just how we roll at Geometrica.  Stroke smoothing on both marker and eraser

Imitates the various sizes of marker a tattooer would typically use to create line drawings, can be customized including a whip shade option..

For doing shading.

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*

We realized early on that if we were going to release a Cory Ferguson drawing app, it had to have a dotwork brush, so 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 dots themselves!

hold the Pencil on screen to draw perfectly straight lines that move and stretch until you decide to lift the pencil. Works well with symmetry effects for sharp, industrial images and unexpected designs. Enable it’s “continuous” option for another unique drawing experience.

New patterns each month to inspect, learn from and use in your own drawings and tattoos.

Because we rely on the support of the tattoo community, this app requires a subscription. After the 14 day free trial period ends, the cost of a subscription is approximately $10 USD per month. (Prices may vary depending on location)

Cory Ferguson is a 2nd generation tattooer with 20 years experience tattooing and nearly 30 years in the industry. He is a pioneer of the geometric and dotwork tattoo movement, and has built on his experience drawing and tattooing in that style to create the drawing app he always wished existed.

Great app but a few tweaks are needed

For reference I am using this app on my new iPad Air.

The app works wonderfully and you can create any unique geometric design quickly and easily, however there have been a few occurring problems that make me consider the pros and cons to keeping the app. First of all is that the app occasionally freezes as I’m drawing as well as randomly undoing my strokes as I’m shading. The lack of a singular dot work tool that you can use for shading rather than the big circular one. Some tools are hard to find, such as the option to delete a layer. Drawing into the design is wonderful so this app can do more than just geometric designs, however the lack of a couple of brushes, makes shading a little hard, no selecting tool, and no tool to select a specific color. A recent problem I’ve encountered is that my shading of a color changes saturation randomly and the only way to fix it is to erase the layer and redo my work.
This is still a wonderful and helpful app and I am very likely to keep it despite these quirks, just wanted to express the problems I’m having to hopefully improve the app further.

Seems like a great app but…

Used as an app for creating geometric stencils it’s perfect but there is a glitch where when I click "select background color" it changes it to black with seemingly (no menu pops up)nno ability to change it back. If fixed I would leave 5 stars. Thanks for the work put into this app so far!

False advertising to download minimum $30/month?

I was excited to try this app, but like another reviewer upon downloading I was quickly made aware the only way to even try out the app was to sign up for a one week trial, tying me to either a monthly or yearly subscription, both priced outrageously for what it is. I’m not paying $119/year of a program I couldn’t even try without committing financially.. yes there’s a free week trial, but for any of us that are busy tattoo artists, a week is a short time to give it a chance and remember to cancel the trial before being charged an arm and a leg.. it’s a pity they don’t have a more affordable option to try it out, $10/month would be substantially more logical to see if artists would like to subscribe for longer terms.

Developer Response ,

From one tattooer to another the fact that you haven’t even tried it yet is a shame, so I got you. We have lowered the monthly price to $15US so you can have a chance to check it out and see what it can do. After that, please come back and let us know what you think. -Cory
