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!

Still The Very Best Fractal App.

In my opinion, Frax HD, is the absolute best fractal art app available on the App Store today and this most recent update has made it even better I think.

After the last big update I thought nothing could top being able to create and save video animations of my fractal artwork. But, now being able to paint my individual pieces different colors (outside of the really cool default color spectrum combinations available), well, I'm blown away once again by the wonderful new features added to this application.

This app has allowed me to create fractal design wallpapers that I previously thought were only possible on multi-hundred dollar computer applications. Plus, having the option to render and save copies of my art that are like the highest, high definition resolution I've ever seen or that I even thought were possible. Which are suitable for printing gigantic poster art or just having extremely detailed and crazy HD wallpapers. Well, I just don't believe that you can find a better choice for fractal artwork on the App Store, now or ever.

Thanks so much to the developer for the recent update and new features and for all the hard work you've no doubt put into maintaining and innovating with this application.

Great app, great customer service.

When I first started using this app, I never anticipated how well done it would be. The standard features alone make a great app, the ability to generate and modify your own fractals, or just play around with the standard one that's loaded when you open the app. There is even a visualization mode for the fractals. Don't even get me started on the pro features, the ability to render 50 megapixel images is insane. And all of the different aspects of the fractal that you are able to modify are simply astonishing. You have very precise creative control. I love this app, and recommend it to anyone and everyone. Even without purchasing pro features it's amazing overall.

Exceeds expectations!

I've downloading some fractal apps in the past but this TRUMPS all the other apps combined. They were all trying to do what this app already does. I even upgraded to the pro version, but it's still amazing and fun without doing so. However, the only! issue i've found so far is when you 'swipe' your finger across the screen to scroll through colors, sometimes it scrolls through the colors rapidly fast, while other times, the colors kind of blend and morph into each other slowly. Wish i had control over when it does it without having to restart the app.
