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!

Ratings and Reviews
Inspirational Beauty and Unparalleled Control
This is not only the best fractal app I’ve ever seen, it’s the best all-around visual arts app I’ve ever used. It may very well be the best app in the App Store. Although it does indeed get rave reviews and is highly respected industry-wide, I still don’t think it gets the recognition it deserves. I may sound like an a company spokesman - and if I were famous, I would be! - but I’m just a devoted fan. The program this team created to allow us to fly through the complexities of the Mandelbrot set in real time - all the while enabling us to create eye-popping artwork using simple gestures and an interface that disappears rather than distracts - is truly miraculous. I cannot understand how anyone could rate this less than 5 stars. I’d give it more if I could, and I bet you will too if you spend a little time learning how it works, followed by endless hours of exploring the creativity and beauty it allows you to express. The new release just adds to the awesome with new fractals, features, and hidden gems...
Let's start by saying this WAS an amazing app...
But I've already paid full price for the pro version of both ipad and the iphone apps... And I feel pretty cheated right about now with the release of a single app. Hell, I've only had them both about a month now... Not very happy about this at all.
After having the chance to fully look into the new version, on my ipad pro, I can honestly say that I'm furious. You've reduced the maximum resolution by HALF, and I can't for the life of me see how you thought a bunch of amorphous blobs of color were going to replace crisp, clear, well-defined fractals without anyone noticing. It's painfully obvious that the quality is squarely half of that in the version you're replacing. At this point, I wish I had not checked the app out this morning, because I felt far less taken advantage of before when there was only the fact that I paid twice for what was now going to be one product. Now, I'm seeing that not only did I get ripped off, but taken for a ride as well, with you not only delivering less in quantity but also tremendously less in quality. This was a poorly considered decision on your part and one that in the end benefits only you, to the detriment of your once happy customers, who are now just highly offended at best. A refund and heartfelt apology are most definitely in order, and would be at the very least, a promising start towards correcting this blunder. 🤦🏻♀️🤷🏻♀️😒
Developer Response ,
Hi Miss Kristan,
The on-screen resolution of the new Universal app should be exactly the same as the previous separate versions, and it now allows image export at larger sizes up to 8192x8192 within the app (with Pro). On the 'Share' panel, press and hold the 'Save Image' button to select the resolution you want. Please send us an email at firstname.lastname@example.org and we'll make all of this right. Thanks!
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.
