Description of Fractally

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, depending on the amount of memory in your device. 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.

Reviews of Fractally

  • Pretty neat but…

    I can’t zoom in infinitely as it makes me nor able to zoom in after a few zooms

    Developer Response

    Yes, the zoom's are limited - to 10,000,000,000,000 x. At the point the zoom's stop, the app has reached the limit of the double precision floating point (IEEE double) precision. Double precision floating point uses 52 bits for its mantessa, 11 bits for the exponent, and a sign bit making 64 (FP64.) To zoom further we need arbitrary precision floating point, and I've experimented with this, but its horribly slow. The hardware handles FP64 and things like multiply and add take one cycle. With arbitrary precision, this goes up to many dozens of cycles per multiply. The app would be sluggish beyond reason - and your review would be complaining about how slow the app is, instead of how its zooms are limited haha. I've favored speed and interactivity in the app over infinite zooms. Trust me, this is the better tradeoff.
  • loads. does nothing.

    nothing you click on does anything. Not sure that this app actually works. Deleted.

    I just noticed this review, 7 months late, oops, sorry for the delay. The app does work, but I noticed a problem that happened when I first ran the app and the view was completely zoomed out, where the menus and buttons were unresponsive. Then I zoomed in (via the pinch gesture) and everything works again. Now I can't reproduce the issue no matter what I do. Strange. I have no idea why the app froze like that - but if you can zoom in (via pinch, scroll wheel, etc) then the app should "unlock". Also, this issue seems to not affect very many people, as many others are downloading the app and using it. If you are curious about the Mandelbrot set, Julia set or the Mandelbrot orbit shapes, the app is definitely worth a spin. Try again. Also, I can be contacted at fractally@luckgrib.com, that is a better route to resolve an issue than an app store comment, if you are interested in resolving the issue.

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