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!

Pretty good...

This app is really good. The only thing that really keeps it from being great is the GUI. When it comes to the gestures you use to change the color, texture, lighting, etc., the gestures aren't intuitive. I've been using this app for a while and I'm still not entirely sure what they are. I've gone through the tutorial more than once, but they're not intuitive, so they just don't stick with me. The fractals are great to navigate and alter, but with the gestures being so unintuitive, it's hard to get things as I really want them. I feel like the great images I've come up with are more a matter of luck than choice. I also don't really like the layout of the controls. I just found some menu that I didn't even know was there, after using the app for a while. One of the foundations of GUI design is that it should be self-explanatory. So, while I do love playing with the app, I also feel that the GUI could really stand to be improved. It's a great idea for an app, though. I love math and I love fractals. It really showcases the beauty of math and allows people to be able to play with it -- something I wish they did more of in Math classes.

They Took Away The 4K Export.

I've always championed and supported this incredible tool a lot and I still believe that it's the best if its kind available on mobile.

But, I'm giving it three stars because I'm very unhappy that they removed the in-app 4K Resolution export option in this most recent update. I've purchased tons and tons of the in-app purchase credits for the super high definition renders, so I hope taking away 4K wasn't some shady idea to get people to want to buy credits.

If so, well that is unethical and messed up. I have like thousands of credits that I have purchased to show my support and appreciation to the developers for this wonderful application.

Also, the Square option was removed from render sizes in this most recent update as well.

Please bring back the 4K and Square render options. I paid for the app on both my iPhone and iPad and bought many, many credits and I don't appreciate you removing features from this application, an app that I paid good money for and expected it to keep the options that were there when I first purchased the program. Thanks and God bless.

Great resolution & zoom in n out

Beware the mere "gallery" viewing fractal apps. The resolution is an offense and their static still are an offense... ok ok you get me...
This is the best I've seen unless you are a math/geometry person. Much much more than the gallery stuff.
I'm an "old time" fractal explorer from the days of clunky software written by enthralled devotees, to modern mind blowing stuff on desktops, including the first glimpse of alien life in "flame" fractals...
_This app_ //really// gives you the thrill of the infinity of fractals; the diversity beyond what our eyes can see in Life all around. Fractal geometry is the math of God.... you'll feel that ....
Hours of exploration, never-ending peace of tweaking jaw dropping views. Resolution that is worthy of viewing fractals.
Salute to whoever picked the entities displayed. Be proud.
