•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 50 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!

Customer Reviews

it’s good, and the pro version even better

I won’t add a long list of things l like here, as I agree with all the 5 star reviews. I will say that you can have even more fun and creative control if you do the in-app upgrade to the pro version, which gives you an astounding array of creative control with very easy to understand and use controls, with options to render at much higher resolution than the screen, save bookmarks, and more.

And on an iPad Pro, it’s amazingly fast and responsive.

Very well thought out, and I’m so glad I took a look at how fractal rendering has changed since I first played with them 20 years ago. Fascinating and fun. Good for kids (even my cat plays with it) all the way up to those of us with grey hair.

Best of class ... Of any class

Seriously, no other app in the graphics image creation or fractal exploration categories even comes close to this one. It's so far ahead of its time, and has been since it was first introduced. Any reviewer who says its functionality is limited hasn't given it a shot. Years into it, I'm still constantly surprised - and delighted - by the hidden gems it contains.

And the new Paint feature adds enough new functionality to be considered a whole new app. Totally changes the way you work with it, if you want it to. Should usher in a new generation of Frax lovers.

Great Product and Responsive Developer

I love playing with the app to help me unwind at night. The possibilities are endless and the resolution is fantastic. I upgraded to the Pro out of appreciation more than needing additional feautres (not that they aren't worth it!). I had a problem with the upgrade and contacted the developer. One of them got back to me in under 20 minutes, on a Saturday night no less, and walked me through the solution. Gotta love people who stand behind their product. To think this much fun and creativity are available for the price of a cocktail blows me away.
