Description
Fractally allows you to explore beautiful Mandelbrot and Julia set images, while at the same time, helping you gain a greater understanding of what they are.
* interactively zoom and scroll around the images, using standard pinch and scroll gestures.
* watch to see how the Julia set changes as you pan and scroll around the Mandelbrot.
* view Mandelbrot or Julia point orbits, a visual representation of how a point changes as it moves through the iteration.
* many different color schemes are provided.
* control the amount of detail shown through the iteration editor. Over 2,000 iterations per point are possible.
* zoom into the fractals over 1,000,000,000,000 x.
* save and share your favorites, in the app as well as through Messages, Mail and AirDrop.
* save high quality, large or small, anti-aliased images.
Note that the saved images can range in size from thumbnails to wall sized photographs. Images are saved in the lossless PNG image format.
As you find interesting images, share them with your friends. Fractally saves fractal coordinates in a fractally file. When these files are shared with others, they can use the app to explore the region you found.
To help understand the images being shown, try experimenting with low iteration counts, starting at 2, and moving up in steps of 1. As you slowly increase the iteration count, watch to see how the images evolve. At the other extreme, high maximum iterations can be used to reveal great hidden detail in deep zooms.
Fractally is a fresh and clean implementation of the Mandelbrot and Julia sets. No frills, just a high quality, solid, viewer and image generator.
Available, and free, on iPhone, iPad and the Mac. Donations are welcome and appreciated.

Ratings and Reviews
Very good for a free app
My 8 year old has now explored for hours, full of excitement. Overall greaet to play with.
Pros
- very fast, good use of graphics card it seems
- nice split screen option with Julia set
- simple but elegant interface, including simple colour option cycling
Cons
- Max iterations at 2k, but takes you to 1e10 zoom nicely
- Zoom of pan and scroll using bottom bar is visually smooth though I found it a bit clunky
Takes me back to playing with 'Dragon' on Silicon Graphics workstations in the 90s
What fun - zooming into the edge of the Mandelbrot set, Julia sets updating almost instantaneously - nice set of colour palettes - trip down memory lane but with breakneck speed - what's not to like!
Developer Response ,
I was also around in the 90's using SGI workstations and "reality engine"s, watching graphics come alive. Good times. Our computers, and phones(!) are so much more powerful today. It's hard to comprehend how fast they are. Thanks for your review!
This Game Is Gas
Thank you for this wonderful game, keep cooping up more
