Frax is an art program that puts the “equations of nature” in the palm of your hand. Frax is powered by fractal geometry, the same principle that creates patterns of self-similarity in our natural world. From spiral galaxies to hurricanes, from tree limbs to branching blood vessels, the universe is filled with endless variation and staggering beauty. Frax visualizes this natural geometric code, so you can explore vast animating digital landscapes and make a masterpiece on your touchscreen.

Zoom deep into your creations. Use multi-touch gestures to fly through and explore intricate shapes and patterns. Tilt-to-steer through animating digital worlds, as you challenge yourself to chart a course for a long and beautiful flight –all at a depth range of a trillion-to-one.

Unleash your inner artist with complex color gradients to smoothly tint and shade your fractal shapes, two light sources for glossy reflections, and novel textures. The combinations are endless: supersmooth or wildly chaotic, metallic sheen or pearly white, subtle shades, stark monochrome or screaming supergloss. Or upgrade to Pro to access almost 100 parameters and controls!

Then share your creations with your friends via Facebook, Twitter and text. Or invite other users to step into your animating world by sharing a live preset link. You can render high-quality images to your photo library or create ultra-high quality 200 Megapixel renders with an IAP. And for the first time, you can now record VIDEO of your Frax animations directly within the app! (Pro IAP required.) Our users have put their designs on canvas, posters, scarves, T-shirts and textiles. The creative possibilities are endless!

What will Frax inspire in you?

We hope you enjoy Frax!

Amazing, gorgeous visuals

I’m not the type that usually writes reviews, but I have to say that this app is beyond compare. I stumbled on it while looking for a music visualization app to cast to my TV (which I only found complete garbage). The quality of the textures is a true test and looks amazing on a Retina display. This app isn’t technically a “game” but so far I’ve spent many hours just playing with the gorgeous fractals. There’s a free version of the app as well but as soon as I saw the stunning fractals, I paid for the the pro version. Seriously this is probably one of the best apps I’ve ever seen. Now I’m going to dig into the math behind the beautiful visuals of these fractals. Just buy this app.

PS. With the pro version you can record videos, I have been converting them to “Live Photos” and using them as wallpapers.

Phenomenal app

Everything i was looking for a fractal app to be like, and much much more. So entertaining to look at, pass time and make beautiful unique creations. Highly recommend it to anyone. Amazing.

I do wish however I could have a rainbow setting on color where it switches colors all over without me needing to press anything (I realize i can make the colors swirl, but its basically the same certain colors until i change the scheme with the color wheel thing)

Frax: An Extension of Abstract Expression

Written by 2D/3D Animator & Director Connor Dunham
Director of the PROJECT VANILLA Trilogy

Frax is a necessary visual abstract tool to create and express mathematical fractal animations, but it’s much more than that. Frax is in a unique place on the App Store. Just like Mextures, Frax is an extension of the ability to create art, albeit: purposely unrealistic, mythical worlds. Frax is different, the app empowers in ease of use, empowering in ability to transfix, and the ability to express a wide-variety of thought through being able to fully customize color, shape, form, mood, saturation, details, spectrum, texture & contours.

I use Frax everyday. To both make how and what I feel, and to use the app to design and create worlds for the 2nd film in my planned trilogy of 2D Fractal Animation, titled PROJECT VANILLA.

Frax is essentially, an extension of abstract color expression, available on the App Store.
