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.

Good, not great

The zoom and pan controls to find interesting areas to explore are great. Resolution is outstanding. Seeing the interation between sets is facinating. Only wish that there was more contol over the color pallet

This is a Great! fractal app. I highly recommend it & I have spent many hours using a variety of such applications.
Enjoy :-)

Desperately needs color cycling

C'mon man, that's been around for 30 years with this stuff. Decent program that needs clearer navigation. At least on Mac.
