Originally created to be able to design the June cover for Brain magazine (
) on my iPad from start to finish, Julia lets you explore a 3-dimensional fractal and render out high resolution images.

** Please note, only iPhone 5s, iPad Air and iPad Mini Retina are supported. Julia will still run on lower end devices, but the experience will be frustratingly slow. **

Thanks to Tom Beddard ( ) for his Open Source Mandelbulb shader.

Phenomenal, needs documentation

This app is ridiculously powerful, inspiring and pretty mesmerizing. The only issues I have with it are lack of documentation, and issues with visual tearing when rendering certain complex models at 4K. I'm running this on a 2017 iPad tho so maybe it would produce consistent renders on an iPad Pro. At first this feels like a toy, but spend a few minutes messing with it and you'll be blown away!

The Best IPhone Rendering Program, Period

This is probably the best tool on a phone you can get for creating wonderful images, check my Instagram where I make daily renders out of this app: Emptism_R, I am passing the 200 rendering mark soon! After using this program for 4 months, I am still getting better at it, it is like a universe where you get to discover and create its beauty....such a wonderful rendering program! Btw I never used any other rendering program yet I still get the hang of this just after a few days of exploring. Thank you developer for making this!

So good, but so frustrating

It really is an excellent app, but it has a steep learning curve with practically no assistance or instruction on what does what. Positioning your design is an exercise in frustration. Finally, adjust a value wrong and the app crashes. You will have to delete and download again. When you do get the look you wanted, it is a beautiful site.
